Si L2,3 emission features are observed above the conventional Si valence band maximum, with intensity scaling linearly with S concentration. The lineshape of the S-induced features change across the insulator-to-metal transition, indicating a significant modification of the local electronic structure concurrent with the change in macroscopic electronic behavior. The relationship between the Si L2,3 XES spectral features and the anomalously high sub-band gap infrared absorption is discussed.}, language = {en} } @inproceedings{KrauseKrautzLehmannetal., author = {Krause, S. and Krautz, Hans Joachim and Lehmann, J. and Luschtinetz, Thomas and Kruse, T.}, title = {Operating regime of a hydrogen-storage-loop power plant of grid relevant dimensions}, series = {Proceedings of the 14th International Symposium on Heat Transfer and Renewable Sources of Energy, Szczecin-Miedzyzdroje, Poland, September 06-09, 2012}, booktitle = {Proceedings of the 14th International Symposium on Heat Transfer and Renewable Sources of Energy, Szczecin-Miedzyzdroje, Poland, September 06-09, 2012}, publisher = {Wydawnistwo Uczelnianie ZUT}, address = {Szczecinie}, isbn = {978-83-7663-121-9}, language = {en} } @misc{BaerSchubertMarsenetal., author = {B{\"a}r, Marcus and Schubert, Bj{\"o}rn-Arvid and Marsen, Bj{\"o}rn and Wilks, Regan G. and Blum, M. and Krause, S. and Pookpanratana, Sujitra and Zhang, Y. and Unold, Thomas and Yang, W. and Weinhardt, Lothar and Heske, Clemens and Schock, Hans-Werner}, title = {Cu2ZnSnS4 thin-film solar cell absorbers illuminated by soft x-rays}, series = {Journal of Materials Research}, volume = {27}, journal = {Journal of Materials Research}, number = {8}, issn = {2044-5326}, doi = {10.1557/jmr.2012.59}, pages = {1097 -- 1104}, abstract = {In view of the complexity of thin-film solar cells, which are comprised of a multitude of layers, interfaces, surfaces, elements, impurities, etc., it is crucial to characterize and understand the chemical and electronic structure of these components. Because of the high complexity of the Cu2ZnSn(S,Se)4 compound semiconductor absorber material alone, this is particularly true for kesterite-based devices. Hence, this paper reviews our recent progress in the characterization of Cu2ZnSnS4 (CZTS) thin films. It is demonstrated that a combination of different soft x-ray spectroscopies is an extraordinarily powerful method for illuminating the chemical and electronic material characteristics from many different perspectives, ultimately resulting in a comprehensive picture of these properties. The focus of the article will be on secondary impurity phases, electronic structure, native oxidation, and the CZTS surface composition.}, language = {en} } @misc{MirskyRieplKrauseetal., author = {Mirsky, Vladimir M. and Riepl, Michael and Krause, Christian and Novotny, Ivan and Splonskowski, Markus and Rehacek, Vlastimil and Tvarozek, Vladimir and Hummel, Helmut and Wolfbeis, Otto S.}, title = {Thin film electrodes for capacitive chemo- and biosensors: an optimization of the electrodes geometry}, series = {Materials Science Forum}, volume = {287-288}, journal = {Materials Science Forum}, issn = {1662-9752}, doi = {10.4028/www.scientific.net/MSF.287-288.423}, pages = {423 -- 426}, language = {en} }
