Abstract  Cr-doped CdS nanowires were synthesized in large scale through thermal co-evaporation of CdS and metal Cr powders. General morphology, detailed microstructure and optical properties were characterized using various techniques. Devices consisting of individual Cr-doped CdS nanowire were fabricated and they exhibited remarkable rectifying characteristics. I-V curves of individual Cr-doped CdS nanowire devices demonstrate that the present nanowires are n-type doped and have high conductivity (10.96 $\Omega$ -1cm-1, indicating great potential applications in nanoscale electronic and optoelectronic devices.
Keywords:  CdS nanowires      electrical properties      luminescent properties
