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} } @misc{LippertDabrowskiOberbecketal., author = {Lippert, Gunther and Dabrowski, Jarek Marek and Oberbeck, Lars and Schroeder, Uwe and Costina, Ioan and Lupina, Grzegorz and Ratzke, Markus and Zaumseil, Peter and M{\"u}ssig, Hans-Joachim}, title = {Morphology and composition of selected high-k materials and their relevance to dielectric properties of thin films}, series = {Journal of the electrochemical society}, volume = {155}, journal = {Journal of the electrochemical society}, number = {5}, issn = {1945-7111}, doi = {10.1149/1.2875741}, pages = {G97 -- G114}, language = {en} } @misc{LukosiusDabrowskiLiskeretal., author = {Lukosius, Mindaugas and Dabrowski, Jarek Marek and Lisker, Marco and Kitzmann, Julia and Schulze, Sebastian and Lippert, Gunther and Fursenko, Oksana and Yamamoto, Yuji and Schubert, Markus Andreas and Krause, Hans-Michael and Wolff, Andre and Mai, A. and Schr{\"o}der, Thomas and Lupina, Grzegorz}, title = {Metal-free, CVD Graphene synthesis on 200 mm Ge / Si(001) substrates}, series = {ACS Applied Materials and Interfaces}, volume = {8}, journal = {ACS Applied Materials and Interfaces}, number = {49}, issn = {1944-8244}, doi = {10.1021/acsami.6b11397}, pages = {33786 -- 33793}, language = {en} } @inproceedings{LippertJessenKoehler, author = {Lippert, Gudrun and Jessen, Markus and K{\"o}hler, Hans-Peter}, title = {Vergleich von Homogenisierungsmethoden zur Probenvorbereitung f{\"u}r die TN- und TP-Bestimmung von Gew{\"a}sserproben}, series = {Ergebnisse der Jahrestagung 2017 der Deutschen Gesellschaft f{\"u}r Limnologie (DGL) in Cottbus}, booktitle = {Ergebnisse der Jahrestagung 2017 der Deutschen Gesellschaft f{\"u}r Limnologie (DGL) in Cottbus}, publisher = {Eigenverlag der DGL}, address = {Hardegsen}, isbn = {978-3-9818302-2-4}, pages = {269 -- 275}, language = {de} } @misc{GastingerMeyerShardinetal., author = {Gastinger, Ingo and Meyer, F. and Shardin, Anton and Ptok, Henry and Lippert, Hans and Dralle, Henning}, title = {Untersuchungen zur Hospitalletalit{\"a}t in der Pankreaschirurgie}, series = {Der Chirurg}, volume = {90}, journal = {Der Chirurg}, number = {1}, issn = {1433-0385}, doi = {10.1007/s00104-018-0654-x}, pages = {47 -- 55}, language = {en} }
