Yttrium Tantalum Oxynitride Multiphases as Photoanodes for Water Oxidation
Wenping Si, Zahra Pourmand Tehrani, Fatima Haydous +4
Perovskite yttrium tantalum oxynitride is theoretically proposed as a promising semiconductor for solar water splitting because of the predicted bandgap and energy positions of ban…
Towards Photoferroic Materials by Design: Recent Progresses and Perspective
Ivano E. Castelli, Thomas Olsen, Yunzhong Chen
The use of photoferroic materials that combine ferroelectric and light harvesting properties in a photovoltaic device is a promising route to significantly improve the efficiency o…
Anisotropic Proton and Oxygen Ion Conductivity in Epitaxial Ba2In2O5 Thin Films
Aline Fluri, Maths Karlsson, Marco Bettinelli +3
Solid oxide oxygen ion and proton conductors are a highly important class of materials for renewable energy conversion devices like solid oxide fuel cells. Ba2In2O5 (BIO) exhibits…
Determination of conduction and valence band electronic structure of LaTiOxNy thin film
Markus Pichler, Jakub Szlachetko, Ivano E. Castelli +5
The nitrogen substitution into the oxygen sites of several oxide materials leads to a reduction of the band gap to the visible light energy range, which makes these oxynitride semi…
