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 I254nm/Idark ratio of 103, and rise (τr = 9 ms) and decay (τd = 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. [ABSTRACT FROM AUTHOR]
