β-Ga2O3 nanorod arrays with high light-to-electron conversion for solar-blind deep ultraviolet photodetection
Vertically aligned nanorod arrays (NRAs), with effective optical coupling with the incident light and rapid electron transport for photogenerated carriers, have attracted much interest for photoelectric devices. Herein, the monoclinic β-Ga 2 O 3 NRAs with an average diameter/length of 500 nm/1.287 μ...
