ZnO nanowire network UV detector demonstration. (a) Schematic illustration of the UV sensors. (b) Transient photoinduced current measurement under UV light with a fixed bias of 1 V. For UV illumination, a UV lamp with the center wavelength at 365 nm is turned on and off alternatively for every 100 s.
