Bi2O2Se/Ta2NiSe5 Tunneling Heterojunction for High‐Performance, Polarization‐Sensitive, and Broadband Infrared Photodetector

Advanced Electronic Materials, EarlyView.
An optimal dynamic balance between carrier lifetime and transit time is achieved in the Bi2O2Se/Ta2NiSe5 tunneling heterojunction, which simultaneously attains high responsivity (>103 A W−1) and a fast response time (≈5 µs). The specific detectivity can reach 3.75 × 1013 Jones at 633 nm and 1.8 × 1010 Jones at 1550 nm. Abstract New technologies such as

Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

Advanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications
