Review on Indium Zinc Oxide Films: Material Properties and Preparation Techniques

Abstract

Thin films have become important for basic studies in physics and in many other fields. The immense interest in basic properties of thin films is due to considerable variations in their properties compared to those of the bulk material. Studies of the optical, electrical and magnetic properties, investigations of structural disorder and phase transition and of various surface phenomena are very much interest in research areas. The results obtained by research on basic studies are useful for the technical application of thin films. Thin films have greater deviations in their behavior corresponding to their original bulk materials. Because of small thickness certain physical features are observed such as optical interference, electronic tunneling through an insulating layer, high resistivity, low temperature coefficient of resistance, increase in optical magnetic fields and optical temperatures of superconductors. Material properties of indium zinc oxide thin films and all the techniques used to deposit thin films are summarized with an elaborative account along with our results.
