In this Letter, we report on the temperature-dependent conductivity and current-voltage curve of a single CdS nanowire, which was synthesized by a simple aqueous chemical growth method. A pair of platinum microleads was fabricated on the single CdS nanowire by focused ion-beam deposition. The room-temperature conductivity and the band gap of the single CdS wire are 0.82 Ω-1 cm-1 and 0.055 eV, respectively. When the applied electric field is larger than 1090 V cm-1, the CdS nanowire shows a nonlinear I-V curve at room temperature.
