An Extensive Study of Main Issues and Techniques to Tenderize the Structural, Electricals, Optical and Magnetic Properties of Thin Films

Abstract

Nano has made a significant role for the development of the semi conductor materials. It has offered tremendous innovation in semiconductor industry also. present paper discuss about the various processing and process for determining the issues and techniques to tenderize the structural, Electricals, optical and magnetic properties of thin films The most interesting properties of ZnO are its wide band gap and its high exitonic binding energy (60 meV) at room temperature which is much higher than that of ZnSe (20 meV), GaN ( 21meV). Because of this, it is expected that ZnO based devices will be more efficient. It also has peizo electric properties. It is unique having semi conducting, piezoelectric, and pyro-electric properties. Historically it is used as white pigment in watercolour and paints, and also an activator in the rubber industry. Further, Today it is expected that it can be used in fabrication of Solar cells ,Laser Diode ,UV-lasers,Thin film transistors, Transparent conductive contacts ,Surface acoustic wave devices ,Thin film gas sensors
