Structural and electrical properties of sol-gel spin coated indium doped cadmium oxide thin films

Abstract

The indium doped CdO thin films have been prepared by the sol-gel spin coating technique and the influence of indium doping concentration on the structural and electrical properties of the deposited films has been investigated. The indium doping concentration in the solution has been varied from 0-10 wt% insteps of 2wt%. A indium doping concentration of 6wt% has been found to be optimum for preparing the films and at this stage a minimum resistivity of 5.92×10−4Ω cm and a maximum carrier concentration of 1.20×1020cm−3 have been realized.
