Figure 2. Photoresponse measurement of the printed ZnO GNWs photodetectors.

Figure 2

(a) Optical image of an all printed GNW photodetector. Scale bar, 50 μm. (b) Schematic of a printed ZnO GNWs photodetector under UV illumination. (c) Time domain photoresponse of a GNW photodetector with five NWs under UV irradiance of 77.5 μW cm−2 at +1 V bias voltage. (d) I–V curves of the printed GNW photodetector under dark, 0.5 nW cm−2, 768.5 nW cm−2, and 115.5 μW cm−2 of UV illumination at +1 V bias voltage.
