An advanced visible/infrared dual-band photodetector with high-resolution imaging at room temperature is proposed and demonstrated for intelligent identification based on the 2D GaSe/GaSb vertical heterostructure. It resolves challenges of producing large-scale growth, achieving fast response speed, outstanding detectivity, lower manufacture cost, which are main obstacles industrialization 2D-materials-based photodetection.
