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…
Suppressed charge recombination in hematite photoanode via protonation and annealing
Wenping Si, Fatima Haydous, Ugljesa Babic +2
Hematite as promising photoanode for solar water splitting suffers from severe bulk and surface charge recombination. This work describes that a protonation-annealing treatment can…
Real-time monitoring of stress evolution during thin film growth by in situ substrate curvature measurement
Elisa Gilardi, Aline Fluri, Thomas Lippert +1
Strain engineering is the art of inducing controlled lattice distortions in a material to modify specific physicochemical properties. Strain engineering is applied for basic fundam…
