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

open access: yesChemSusChem, 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.

Dirac‐Source Linear X‐Ray Detection Diode

open access: yesAdvanced Functional Materials, EarlyView.
Monolayer graphene imparts near linear current‐voltage behavior to a perovskite X‐ray detection diode, contrasting with conventional diode‐like responses. Exploiting graphene's Dirac dispersion and a Schottky‐like back‐to‐back junction, the device achieves six‐orders‐of‐magnitude dark current suppression while retaining linearity over 200 V, enabling ...
