Abstract

Abstract A self‐powered, high‐performance Ti 3 C 2 T x MXene/GaN van der Waals heterojunction (vdWH)‐based ultraviolet (UV) photodiode is reported. Such integration creates a Schottky junction depth that is larger than the UV absorption depth to sufficiently separate the photoinduced electron/hole p...
