Controlling the Electronic Structures of Perovskite Oxynitrides and their Solid Solutions for Photocatalysis

ChemSusChem, 2016
AbstractBand‐gap engineering of oxide materials is of great interest for optoelectronics, photovoltaics, and photocatalysis applications. In this study, electronic structures of perovskite oxynitrides, LaTiO2N and SrNbO2N, and solid solutions, (SrTiO3)1−x(LaTiO2N)x and (SrTiO3)1−x(SrNbO2N)x, are investigated using hybrid density functional calculations.

From Heterostructures to Solid‐Solutions: Structural Tunability in Mixed Halide Perovskites

Advanced Materials, 2023
AbstractThe stability, reliability, and performance of halide‐perovskite‐based devices depend upon the structure, composition, and particle size of the device‐enabling materials. Indeed, the degree of ion mixing in multicomponent perovskite crystals, although challenging to control, is a key factor in determining properties.
