The purity of the material was checked by X-ray photoemission spectroscopy. The orientation of the molecules in respect to the substrate plane was investigated by angle-dependent near-edge X-ray absorption fine-structure spectroscopy. The morphology was characterized by atomic force microscopy. Most samples exhibited a significant orientation that was accompanied by crystalline structures; others had no orientation at all with a dominant amorphous morphology. This behavior indicates that several preparation parameters affect the crystallinity and the orientation of the phthalocyanines.}, language = {en} } @techreport{HenkelPaloumpaOpreaetal., author = {Henkel, Karsten and Paloumpa, Ioanna and Oprea, A. and Appel, G{\"u}nter and Schmeißer, Dieter and Frandsen, W. and Sch{\"o}lzel, Mario}, title = {Entwicklung von Sensoren mit Elektroden aus leitf{\"a}higen Polymeren}, language = {de} } @article{MikaloAppelHoffmannetal., author = {Mikalo, Ricardo Pablo and Appel, G{\"u}nter and Hoffmann, Patrick and Schmeißer, Dieter and Mast, M.}, title = {Multi-Atom Resonant Photoemission applied to study the silver to nitrogen interaction in polypyrrole films}, language = {en} } @article{SchmeisserAppelBoehmeetal., author = {Schmeißer, Dieter and Appel, G{\"u}nter and B{\"o}hme, O. and Heller, Thomas and Mikalo, Ricardo Pablo and Hoffmann, Patrick and Batchelor, David R.}, title = {Nanoparticles and polarons: active centers in thin film sensor devices}, language = {de} } @article{AppelMikaloHenkeletal., author = {Appel, G{\"u}nter and Mikalo, Ricardo Pablo and Henkel, Karsten and Oprea, A. and Yfantis, Alexandros D. and Paloumpa, Ioanna and Schmeißer, Dieter}, title = {Polymeric Electrodes}, language = {en} }
