High‐Performance (hk0)‐Oriented Sb 2 S 3 Photodetectors Toward Diversified Optoelectronic Applications

ABSTRACT Broadband photodetectors that simultaneously combine low standby energy consumption, adequate photosensitivity, fast response rate, and scalable integration compatibility remain challenging to realize. Herein, Sb 2 S 3 thin films have been prepared through pulsed‐laser d...

Visualizing Heteroepitaxy of Angle-Oriented GeSe/WSe2 Heterostructures for Near-Infrared Ultrasensitive Photodetectors

Abstract Precise heteroepitaxial control in van der Waals (vdW) heterostructures remains a challenge. Here, we demonstrate a visualized and directed heteroepitaxy strategy for GeSe on WSe2 by integrating in situ imaging with symmetry-guided physical vapor deposition. Real-time ob...
