Influence of W ch and photoresponse characteristics. a Measured I-V curves of the ZnO NRA-based PDs grown at 25 mM with different W ch of 5, 15, and 30 μm and b photoresponse characteristics of the ZnO NRA-based PDs grown at 25 mM with W ch of 15 μm under on/off switching of light illumination. The inset of a also shows the photocurrent on-off ratio with different W ch from 5 to 30 μm
