High capacitance density and dielectric permittivity must be accompanied by extremely low leakage currents (10-8 A/cm2) at bias 0.5 V. To achieve such low leakage currents, high band gap and proper band alignment is required. Occupied electronic states can be probed with standard laboratory photoemission methods. Probing of unoccupied states is more challenging. Synchrotron based PES in combination with XAS forms a powerful method to study the band alignment. ASAM end station located at the U 49/2 PGM 2 beamline of BESSY II (Berlin) offers excellent conditions for performing such measurements. We investigated HfO2 - based alkaline earth perovskite - BaHfO3 with subsequent admixture of TiO2, resulting in formation of BaHf0.5Ti0.5O3 compound. The analysis of data indicates that band gap for HfO2 is similar to BaHfO3 and amounts 5.8 eV; for BaHf0.5Ti0.5O3 it decreases to 3.8 eV. We conclude that the addition of TiO2 to BaHfO3 increases significantly the dielectric permittivity but also impacts the band gap alignment. The conduction band offset shrinks, influencing the leakage current behavior.}, language = {en} } @incollection{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Endler, Ricarda and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Magri, Fabien and Meinert, Peter and Moeck, Inga and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {Geological Storage of CO2 - Long Term Security Aspects}, editor = {Liebscher, Axel and M{\"u}nch, Ute}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-319-13929-6}, pages = {183 -- 209}, language = {en} } @inproceedings{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Thomas and Wechler, Klaus-Peter}, title = {Reconstructing spatial and temporal patterns of soil formation in an anthropogenic drift sand area in Northeastern Germany}, series = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, booktitle = {European Geosciences Union, General Assembly 2015, Vienna, Austria, 13 April - 17 May 2015}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @misc{ZaumseilYamamotoSchubertetal., author = {Zaumseil, Peter and Yamamoto, Yuji and Schubert, Markus Andreas and Schr{\"o}der, Thomas and Tillack, Bernd}, title = {Heteroepitaxial Growth of Ge on compliant strained nano-structured Si lines and dots on (001) SOI substrates}, series = {Thin Solid Films}, volume = {557}, journal = {Thin Solid Films}, issn = {0040-6090}, pages = {50 -- 54}, language = {en} } @incollection{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Endler, Ricarda and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Magri, Fabien and Meinert, Peter and Moeck, Inga and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {Joint Research Project Brine: Carbon Dioxide Storage in Eastern Brandenburg;

Multiple reshaping since the Late Glacial considerably changed the landscape up to and including especially historic times. Sediment sequences and (fossilized) soils can improve our understanding of Late Quaternary landscape development, but mapping of buried soils and surfaces is often limited to single outcrops. Ongoing archaeological rescue excavations in the pre-field of the open-cast mine Cottbus-Nord (northeastern Germany) with dense excavation trenches in an about 10 ha dune and drift sand area reveal multilayered sediment sequences with fossilized soils and sediments from the Late Pleistocene to the Late Holocene. Archaeological findings ranging from Mesolithic flint stones to an about 200 year old ceramics in eolian sediments covering plow horizons and wheel tracks suggest that eolian relocation of sandy material was intensive about 200 years ago. Still unpublished OSL dating underline the intense eolian activity. Recent studies showed that between the 15Th to the 19Th century an iron smelter 5 km to the west of our study site was supplied with charcoal, which was produced in a forest 5 km east to our study site. Our current findings about Late Holocene eolian activity raise the question if this eolian reshaping of the landscape is connected with the operation of the iron smelter either directly by transport or bog iron ore winning or indirectly by population pressure caused by the prospering iron smelter. Our ongoing research indicates, that already for historic land-use off-site effects causing further landscape changes have to be considered.}, language = {en} } @misc{WilczekTrieschmannSchulzeetal., author = {Wilczek, Sebastian and Trieschmann, Jan and Schulze, Julian and Sch{\"u}ngel, Edmund and Brinkmann, Ralf Peter and Derzsi, Aranka and Korolov, Ihor and Donk{\´o}, Zolt{\´a}n and Mussenbrock, Thomas}, title = {The Effect of the Driving Frequency on the Confinement of Beam Electrons and Plasma Density in Low Pressure Capacitive Discharges}, series = {Plasma Sources Science and Technology}, volume = {24}, journal = {Plasma Sources Science and Technology}, number = {2}, issn = {0963-0252}, doi = {10.1088/0963-0252/24/2/024002}, pages = {024002}, language = {en} } @misc{GallianTrieschmannMussenbrocketal., author = {Gallian, Sara and Trieschmann, Jan and Mussenbrock, Thomas and Brinkmann, Ralf Peter and Hitchon, William N.
