Laser Ablation Synthesis of Metal Nanocrystals Contained Silicon Nanowires

摘要

We report a new kind of nanosized composite of a transition metal nanocrystal array distributed in a silicon nanowire, which is fabricated by the laser ablation of transition metal contained silicon target at high temperature. The diameter distribution of the nanowires and nanocrystals in the wire are homogeneous. The combination of the nanosized silicon wires and metal nanocrystals make the material of the interest both in the fundamental research and the possible nano-element of device.
