Design of CsSnBr3/Ga2O3 Hybrid Photodetectors for High UV Selectivity and Bifacial Usage

Advanced Theory and Simulations, EarlyView.
A numerical study investigates a lead‐free CsSnBr3/Ga2O3 p–n heterojunction photodetector, analyzing its electrical and optoelectronic performance. High illumination‐to‐dark current ratios and rectification are achieved. The device operates in self‐powered, bifacial, solar‐blind, and UV–Vis modes with strong responsivity and detectivity.

First‐Principles Investigation of the T‐ and M‐Centers in Silicon Using Meta‐GGA Functionals

Advanced Theory and Simulations, EarlyView.
The relaxed structure for (a) T‐center and (b) M‐center. The calculations on the T‐center demonstrate excellent agreement with the HSE06, reinforcing the efficiency of meta‐GGA approaches for accurate defect characterization in Si. The M‐center is introduced, revealing promising quantum optical properties.
