Figure 5

Photoconduction spectra of a single crystal NW device (a) and a GNW device (b), with wavelength ranging from 300 nm to 800 nm. (c) The corresponding responsivity and photoconductive gain versus incident wavelength of the GNW device. (d) The corresponding detectivity versus incident wavelength of the GNW device.
