Rectifying characteristics and solar-blind photoresponse in β-Ga2O3/ZnO heterojunctions |
Plots of time-dependent photoresponse of the β-Ga2O3/ZnO heterojunction under illumination of 254-nm wavelength light at different switching on/off bias voltages: (a) −7 V, (b) −5 V, (c) 0 V, and (d) 5-V bias. |
