Abstract

Self-powered flexible solar-blind photodetectors based on WSe₂/β-Ga₂O₃ 2D/3D van der Waals (vdW) heterojunctions were manufactured, which exhibit brilliant optoelectronic performances with a low dark current of 136 fA at 0 V, a I_254nm/I_dark ratio of 10³, and rise (τ_r = 9 ms) and decay (τ_d = 18 ms) times. In a further step, a solar-blind communication system was fabricated with a good information transmission capability and low energy consumption. Furthermore, “AND” and “OR” optoelectronic logic gates have been realized, which can be applied to signal processing in the field of solar-blind communication.
