ERRATUM: Revisiting Duffy's model for Sb3+ and Bi3+ in double halide perovskites: Emergence of a descriptor for machine learning

Optical Materials: X, 2021
The Duffy's model is reformulated for Sb 3+ and Bi 3+ in cubic chloro- and bromoelpasolites with « 0D » perovskite structure. The new equation allows calculating the energy of the first s 2 → s 1 p 1 electron transition from crystal structure data.

Dirac‐Source Linear X‐Ray Detection Diode

Advanced 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 ...
