Effect of Cu Doping on the Conductivity of Individual ZnTe Nanowires

Abstract:

The effect of Cu doping on the conductivity of individual ZnTe nanowires was investigated. Cu was diffused into ZnTe nanowires during the heat treatment process. Cu content was controlled by the thickness of Cu layer sputtered on the top of ZnTe nanowires. I-V curves of Cu doped ZnTe nanowires have been tested by four-terminal measurement. The results indicate that the conductivity of Cu doped ZnTe nanowires is effectively improved. When Cu content doping in ZnTe nanowires reaches 17.5%, there is about five orders of magnitude improvement in the conductivity of Cu doped ZnTe nanowires, compared with undoped ZnTe nanowires.
