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...
