An Ultrahigh Responsivity (9.7 mA W⁻¹) Self‐Powered Solar‐Blind Photodetector Based on Individual ZnO–Ga₂O₃ Heterostructures

Highly crystallized ZnO–Ga 2 O 3 core–shell heterostructure microwire is synthesized by a simple one‐step chemical vapor deposition method, and constructed into a self‐powered solar‐blind (200–280 nm) photodetector with a sharp cutoff wavelength at 266 nm. The device shows an ultrahigh responsivity ... View More
