Broadband Visible−Near Infrared Two‐Dimensional WSe2/In2Se3 Photodetector for Underwater Optical Communications

P–n junctions based on 2D materials can be achieved using a selective doping technique, while such a method is challenged by the complex fabrication process. Here, a facile van der Waals (vdWs) structured p–n heterojunction is demonstrated by simply transferring an n‐type multilayer α‐In2Se3 (direct...
