ALD oxygen vacancy-rich amorphous Ga2O3 on three-dimensional urchin-like ZnO arrays for high-performance self-powered solar-blind photodetectors

A high-performance photoelectrochemical (PEC)-type heterojunction-driven solar-blind detector was constructed by atomic layer deposition (ALD) oxygen vacancy-rich amorphous Ga 2 O 3 on three-dimensional urchin-like ZnO nanorod arrays (3D V O -Ga 2 O 3 /ZnO).
