Abstract

A new integrate thermoelectric materials based on silicon nanowires (SiNWs) was described. In this structure , the SiNWs was fabricated by chemical etching technique as the backbone, and then a thin layer of Nickel nanoparticles was plated on the sidewall of SiNWs by elelctroplating and thermal rapid annealing technique which charact erized by Energy Dispersive Spectroscopy (EDS) EDS), and Scanning Electron Microscopy (SEM) to obtain the information on the structural and morphological properties. T he thermoelectric behaviors of Ni/SiNWs ha ve been investigated . It is conclude that the Ni/SiN Ws nanocomposite could realize power output. So the Ni/SiNWs nanocomposite is a good alternative for integrate thermoelectric devices.
