Infrared characteristics of ni-doped ZnO thin films

Abstract

Ni-doped ZnO(ZnO:Ni)thin film had been studied widely as a ferromagnetic semiconductor, but there are far fewer studies on its infrared characteristics. This paper describes experiments in which Ni-doped ZnO thin films were deposited on quartz glass using a sol-gel process with different sintering temperatures. The infrared characteristics and the effects of the different fabrication processes were investigated using various techniques including X-ray diffraction (XRD), SEM and FT-IR.
