Semiconductor nanowires and nanoribbons are being considered as the basis of a variety of device technologies. Recently, ZnO nanowire ultraviolet photodetectors and optical switches have been investigated [1]. The results suggest that they are good candidates for optoelectronic switches. Zhou et al. [2] reported the UV response of SnO2 nanowires and observed a strong modulation of the conductance in SnO2 nanowire by UV illumination. CdS is an important semiconductor with a direct band gap of 2.42 eV that falls in the visible region at room temperature. CdS thin films have excellent photoconductive properties and were used in a large number of solid-state device applications such as photoconductive (PC) detection, xerography, photo-voltaic solar energy conversion, and thin-film transistor electronics. But up to now, only a relatively small effort has been paid to study the photoconductance of CdS nanoribbons [3] and a single nanowire [4], no one reported the...
