Metal/semiconductor hybrids consisting of self-assembled CdS nanoparticles on Cd nanowires

We report on the synthesis and the characterisation ofmetal/semiconductor hybrids consisting of self-assembled CdSnanoparticles on Cd nanowires, which are grown by thermalevaporation of the mixture of CdS and Cr. The growth of the hybridsis attributed to the decomposition of CdS at high temperature andthe strain relieving that arises mainly from the lattice mismatchbetween Cd and CdS. Temperature dependence of zero-field resistanceof single nanohybrid indicates that the as-produced Cd/CdSnanohybrid undergoes a metal--semiconductor transition as a naturalconsequence of hybrid from metallic Cd and semiconducting CdS. Themetal/semiconductor hybrid property provides a promising basis forthe development of novel nanoelectronic devices.
