Zusammenfassung:Van der Waals (vdW) heterojunctions composed of 2D layered materials exhibit novel physical phenomena that can power a range of electronic and photonic applications. Here, the first demonstration of the light switchable mechanism between the rectifier diode and Esaki diode in SnS2/WSe2‐black phosphorus (BP) vdW heterojunctions is presented. In this design, the photogating effect of WSe2‐BP junction is employed as the switch toggle between rectifier diode and Esaki diode. Based on this light switchable mechanism, a super‐linear photocurrent‐power dependence is observed and a high‐performance photodetector with high detectivity (5.1 × 1011 Jones) and rapid response speed (
