T1 - XTEM and TFXRD investigations of ohmic Ti/Al/Ti/Au/WSiN contacts on AlGaN/GaN HFET layer systems JF - Semiconductor Science and Technology N2 - The microstructural features of the high-temperature-stable ohmic contact system Ti/Al/Ti/Au/WSiN on AlGaN/GaN were investigated using analytical transmission electron microscopy and thin film x-ray diffraction. For two typical rapid thermal annealing steps at 750 ◦C (non-ohmic behaviour) and 850 ◦C (ohmic behaviour) the intermetallic phases at the metal–semiconductor interface are presented. Increased annealing leads to the transformation of an Al2Au-AlAuTi phase mixture to a mixture of Al2Au-Al3Au8 phases and the formation of Ti-Al-nitride layers at the interfaces. In light of these results the electrical contact properties are discussed.

For understanding the basic processes occurring during the friction process, information on the surface topography of brake pads and discs is needed, in addition to information about chemistry and thermodynamics. In this paper, samples of pads and discs were analysed using white light interferometry. The topography of the surfaces was measured quantitatively. Using software tools described in a previous paper [Wear 248 (2001) 121], the distributions of area, height, and slope of the contact patches were computed. Characteristic properties of the contact patches were found to describe the influence of the test parameters such as friction power and testing time.

T1 - PowderCell : a mixture between crystal structure visualizer, simulation and refinement tool T2 - Powder diffraction : proceedings of the II International School on Powder Diffraction N2 - The program PowderCell is a crystallographic tool for visualization of Crystal structures. However, it offers also non-conventional features like the fulautomatical generation of subgroups or the consideration of non-standard settings of space-group types. On the one Hand the program is very useful for non-crystallographers who like to get an impression of the atomic arrangement within the unit cell. But also for crystallographers it is recommendable because it contains a lot of additional information which can be extracted and used like data given in the International Tables for Crystallography, Vol. A. However, the most important advantage of the program is the simultaneous calculation of the X-ray or neutron diffraction powder patterns for a mixture of up to 10 crystalline phases. Between more than 7 different characteristic radiations can be chosen and their influence on the resulting powder pattern can be studied. Furthermore, experimental diffractograms can be analysed using a refinement procedure. The implemented LeBail-algorithm allows the investigation of unknown phases. In combination with the refinement algorithm an interface to Shelx offers the possibility for a step by step ab initio structure analysis. Certainly, the user-friendly shell is one reason that especially users who are not so familar with space-group symmetry, crystal structure data or diffractometry use this powerful tool for the solution of scientific or analytical problems as well as in teaching.

T1 - HIIRM final report N2 - Accurate analytical results have become more and more an absolute essential tool for further progresses in technology and science. Precision however, often used in this context as a quality criterion for analytical methods, is not a replacement for accuracy in any way. Therefore, analytical procedures are necessary, which will generate reliable and accurate results and can be used for evaluation of other analytical procedures and certification of reference materials (RM). Especially the certification of reference materials for the amount content of trace elements requires highly accurate results with a small combined uncertainty. The best example for an analytical procedure having this capability is undoubtedly Isotope Dilution Mass Spectrometry, for inorganic as well as for organic applications. Applied on Thermal Ionization Mass Spectrometry (TIMS) isotope dilution provides results of highest quality and proven high accuracy especially in the field of RM certifications for more than 30 years. The major drawback of this approach often is the necessity for a complex chemical separation step. A major advantage of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is the potential to cope with a simplified or an on-line-carried-out sample preparation. A key requirement of isotope dilution analysis however is the accurate and precise determination of isotope ratios, because of its limiting factor for the accuracy and the total uncertainty of the result. Very precise isotope ratios can be determined in combination with a detection system that is capable of simultaneous detection of different isotopes, a so-called multi-collector system. The objective of the presented project is to evaluate the advantages of such a multi-collector ICP-MS for the application of IDMS in the field of trace elemental analysis in reference materials. The focus is on the development of simple and fast procedures for isotope ratio measurements in general and IDMS analysis in particular. Furthermore, it is an objective to develop and evaluate on-line spiking procedures. One of the first conclusions, which had a severe impact on the HIIRM project, arose during the early days of the project. Currently most certification experiments are accomplished by certification campaign based on a variety of participants’ results. The sample preparation, sending, analyzing and data evaluation however require lot of resources and the process may take a long time. An alternative way is given by using fewer participants with methods of higher metrological quality. For elemental amount contents such a method undoubtedly is isotope dilution analysis and multi-collector ICP-MS offers the necessary precision and matrix robustness and ruggedness as said above. Therefore, a multiple collector ICP-MS was manufactured as part of the project instead of the originally planned high-resolution instrument. Due to the novelty of the multicollector ICP-MS instrument, a lot of additional fundamental research became necessary. Especially interferences needed further attention. Fortunately, the IsoProbe is additionally equipped with a high-resolution option and with a brand new collison cell. The high-resolution option however can only be used to identify interferences but cannot be used to quantify them. On the other hand, the use of the collision cell proved to be a vital tool to overcome interferences. This is especially true because high resolution would have reduced the available sensitivity by a factor of ~100. Applying the collision cell technology the high sensitivity was maintained whilst most interferences were eliminated. However finding the right parameters of operation for the collision cell became a huge part of the method development process. A variety of gases like argon, helium, hydrogen, deuterium, nitrogen, krypton and xenon were tested for their suitability. Especially the tests accomplished for iron determinations revealed that carefully selected parameters have an incredible influence on the quality of the final results. Nonetheless collision cell technology will undoubtedly be widely used for newer ICP-MS instrumentation and contribute to eliminate wrong analytical values caused by interferences. The enhanced sensitivity of the instrument revealed also problems not detectable by other means. The control of contaminations seems to be one of the major analytical challenges in the future. Sector field based ICP-MS will give the user an opportunity to trace sources of contamination back to their origin and eliminate them. Even lower limits of detection will be the result as well as an enhanced reliability for analysts dealing with higher amount contents. The analyst will also benefit in controlling blank levels when the method of isotopically spiked procedure blanks is used as demonstrated in this project. Another main part of the project was the validation of the developed procedures. The first validation step was successfully accomplished by applying these procedures on the standard solutions provided by NRG. The main part of this validation however consisted of the evaluation of the fundamental parameters of the isotope dilution process and related measurements. This approach turned out to be superior compaired to the first step as a highly reliable uncertainty calculation can be easily performed. The best reputation and acceptance of the methods can however only be accomplished by participating in certification campaigns or in interlaboratory comparisons on highest metrological level. The results of the participations in general were brilliant. Not only the results but also the obtained realistic uncertainties were of superior quality. Direct comparisons at BAM with the results obtained by a multicollector TIMS applying the same calculation schemes showed the benefits of using multicollector ICP-MS. The main benefits of ICP-MS were identified, of which the first one is the enhanced precision of the isotope ratio measurement. For a variety of elements the values obtained by multicollector ICP-MS are even more precise than the ones obtainable by multicollector TIMS. The second important advantage identified was the simplified sample preparation. The laborious and time consuming analyte-matrix-separation step as necessary for TIMS measurements can either be omitted or at least be drastically reduced. Therefore, the advantages regarding time and enhanced sample throughput will result in further spread of ICP-MS in general and multicollector ICP-MS in particular. The third major part in terms of the method development process was mainly focused on developing an online isotope dilution system. The volumetric instead of the gravimetric IDMS approach proved difficult, if the high demands necessary for RM definition measurements are to be fulfilled. The major obstacle in this case is the missing stability and precision in terms of mass flow. Consequently, the initial development failed as the system made up of two piezoelectric droplet injectors was unable to reach the required stability as well as precision. The thereupon-created system consisting of two HPLC pumps proved to be far more valuable regarding automation and particularly the quantification of transient signals. Nevertheless, such a system will probably be rarely used in certification campaigns, as the gain of time is too small compared to the loss of reliability. However, this system proved most valuable in terms of species-specific elemental analysis as preliminary investigations showed. In this context this system will be suitable for certification measurements, as the major uncertainty contributions derive from sampling, sample treatment and species distribution and as moreover all availabel methods demonstrate far beyond. During the whole project, one of the main concerns regarding the multicollector ICP-MS instrument were software issues caused by the early development state of the original control programs. A lot of effort was necessary to accomplish the necessary data manipulations externally. The development of a new software suite by Micromass for the HIIRM project has solved this issue almost completely. With the new software suite and the validated parameters of measurement a step forward for institutes dealing with reference material certifications was achieved. Future certifications campaigns for minor elemental contents in different matrices should be performed by a small number of participants from highly qualified institutes. These institutes should apply very reliable methods of measurement like the ones developed in the HIIRM project. Many resources may be saved that way while the outcome of the certifications may easily be improved. ICP-MC-MS has the potential to be an important method in this context. Stable isotope dilution analysis in combination with a multi-detector ICP-MS, equipped with a hexapole collision cell for the suppression of important spectral interferences and for enhanced sensitivity, proved to be an advanced method of elemental analysis with a high potential for matrix independent measurements. Since ICP mass spectrometers of this type have only recently been introduced, no systematic evaluation of the capabilities of this specific application of the ICP-IDMS method has yet been made.

Excellent agreement between the results of the different independent methods was found. In the present work, the measurements of the homogeneity of the areal density of Sb, previously determined with RBS in spots having 1 mm diameter, are improved with synchrotron X-ray fluorescence analysis: Higher precision in even smaller sample spots allows to estimate a reduced inhomogeneity of the whole batch of samples of the order of only 0.4%. Thus the uncertainty of the certified value can further be reduced. Down to fractions of a chip with 0.3×0.4 mm2 area, the areal density is now certified as (4.81±0.06)×1016 Sb atoms/cm2, where the expanded uncertainty 0.06 (coverage factor k=2) corresponds to only 1.2%. The relative merits of the different analytical methods are discussed.

Nonionic sugar surfactants produced via different synthetic routes are mixtures of alkyl homologues, oligomers, anomers and isomers. Alkyl homologues and oligomers of alkyl mono- and diglucosides were separated by reversed-phase high-performance liquid chromatography (HPLC) with methanol–water as the mobile phase using a gradient elution. The gradient was optimized in respect to a simultaneous separation of alkyl glycosides according to their alkyl chain length and alkyl polyoxyethylene glucosides with regard to their length of the polyoxyethylene spacer. The separation of alkyl glycosides into ?- and ?-anomers was carried out by normal-phase HPLC with isooctane–ethyl acetate (60:40, v/v)–2-propanol in the gradient mode. Light scattering detection was used. Matrix-assisted laser desorption ionization time-of-flight mass spectra of alkyl glucosides and dodecyl glucosides with oxyethylene spacer groups are presented.

The compound was crystallised from methanol to give colourless prisms, and the crystal structure was determined. The monoclinic space group is P21 with Z=2 and unit cell parameters a=6.6060 (13), b=14.074 (3), c=9.3180 (19) Å, ?=108.95(3)°. The structure was solved by direct methods and refined to R=0.0286 for 2528 reflections. Both glucopyranoses occur in the 4C1 chair conformation with endocyclic bond angles in the range of standard values. The relative orientation of both units described by the interglycosidic torsional angles [? (O-5?---C-1?---O-4---C-4) -89.1°, phi (C-1?---O-4---C-4---C-5) -152.0°] is responsible for the very flat shape of the molecule and is similar to those found in other cellodextrins. Different rotamers at the exocyclic hydroxymethyl group for both units are present. The hydroxymethyl group of the terminal glucose moiety displays a gauche–trans orientation, whereas the side chain of the reducing unit occurs in a gauche–gauche conformation. The solid state 13C NMR spectrum of compound 6 exhibits all 14 carbon resonances. By using different cross polarisation times, the resonances of the two methyl groups and C-6 carbons can easily be distinguished. Distinct differences of the C-1 and C-4 chemical shifts in the solid and liquid states are found.

Enriched phosphoric acid was prepared by hydrolysis of PCl5 with 17O-enriched water and neutralized with sodium carbonate. The sodium metaphosphate was then melted at 800 °C for 15 h and quenched. Polyphosphate and ultraphosphate glass compositions were prepared by remelting the metaphosphate with sodium carbonate and phosphorus pentoxide, respectively. 31P magic angle sample spinning (MAS) NMR was used to determine the Na2O/P2O5 content in the glasses. 17O NMR spectra (quadrupole echo for non-rotating samples and multiple-quantum excitation for rotating samples (MQMAS)) show two oxygen sites in the samples with large quadrupolar coupling constants (4.7 and 7.7 MHz), in accordance with the high phosphorus electronegativity. According to the correlation of 17O quadrupolar constants with bond ionicity, these two components are attributed to bridging P–O–P and non-bridging P–O...Na oxygens. The average P–O–P bond angle is estimated with the quadrupolar asymmetry derived from the fit of the static echo spectra. The MQMAS spectrum shows a distribution of non-bridging oxygen chemical shifts, attributed to a variation of bond length and angle.

Film thickness ranged in the order 10 nm. An attempt was made to estimate the confidence range of the method by comparison with results from other methods of analysis. The data show that in addition to the uncertainty of the spectral intensity measurement and the complicated fitting routine, systematic deviation caused by the underlying model should be added. The scattering in the results from other methods does not enable specification of a range of uncertainty, but deviations from the real thickness are estimated to be less than 20%.

T1 - Active sites on an oxide catalyst for F/Cl-exchange reactions: X-ray spectroscopy of fluorinated y-Al2O3 JF - Physical chemistry, chemical physics N2 - The dismutation of CHClF2 to CHF3 and CHCl3 was used to probe the effect of γ-Al2O3 fluorination on fluorine-against-chlorine (Cl/F) exchange reactions. X-ray photoelectron spectroscopy (XPS), X-ray excited Auger electron spectroscopy (XAES) and X-ray absorption near edge structure (XANES) spectroscopy were employed to probe the modifications at the surface of γ-Al2O3 accompanying the initial stages of fluorination. The results suggest that fluorine uptake by γ-Al2O3 starts initially at the surface of the oxide particles, with the formation of a fluorine species that is characterised by a single bond and a high effective charge q. Catalytic Cl/F-exchange is only observed after accumulation of higher fluorine concentrations, for which insertion of fluorine into the sub-surface region of the oxide crystallites has commenced. Quantitative XPS shows that the fluorination level must exceed approximately 10 atom% of the anions to achieve catalytic activity. The spectroscopic evidence suggests that the formation of aluminium oxofluorides is sufficient to provide catalytic activity. The presence of an AlF3 phase is not a condition for the observation of catalytic activity, even though defect-rich AlF3 is ultimately the endpoint of the fluorination process and is itself a Cl/F exchange catalyst.

T1 - Characterization of interfacial behaviour in carbon-fibre/cyanate composites JF - Composites science and technology N2 - In this study an attempt is made to investigate the influence of surface treatments such as oxidation and sizing on a high-strength carbon fibre in respect of interfacial adhesion in composite materials with a cyanate matrix. For analysing the fibre/resin interfacial adhesion the single-fibre pull-out technique has been used. The interfacial shear strengths obtained by this technique have been compared with results of interlaminar shear strength measurements corresponding to woven composite plates. In order to clarify the nature of this interfacial adhesion, both morphological (by atomic force microscopy, AFM) and chemical characterisation (by Fourier transform infrared, FTIR), have also been carried out.

Scanning electron microscopy and zeta-potential measurements confirmed the presence of a rough but dense and continuous electrocoating with a basic surface character. Therefore, lsquogoodrsquo adhesion behavior between the electrocoated carbon fibers and an epoxy resin matrix should be expected. The interfacial adhesion was measured using the single fiber pull-out and single fiber indentation test. It was shown that only lsquointermediatersquo adhesion was present between the carbon fibers and the electrocoating, but superior adhesion between the coating and epoxy resin exists. The single fiber model composites always failed at the fiber/electrocoating interface. However, as shown by using the indentation test, the interfacial adhesion between fibers and electrocoating can be significantly improved if preoxidized fibers are used as substrate for electropolymerization. A very high tensile strength for the electrocoating can be expected as derived from the single fiber pull-out tests.

In accordance with earlier established models, we found the phenomena amorphization, melting, re-crystallization, nucleated vaporization, and ablation to occur with increasing laser fluence down to the shortest pulse durations. We noticed new morphological features (bubbles) as well as familiar ones (ripples, columns). A nearly constant ablation threshold fluence on the order of 0.2 J/cm2 for all pulse durations and multiple-pulse irradiation was observed. For a duration of ,100 fs, significant incubation can be observed, whereas for 5 fs pulses, the ablation threshold does not depend on the pulse number within the experimental error. For micromachining of silicon, a pulse duration of less than 500 fs is not advantageous.
