Thin film science is a relatively young and ever growing field in science and technology, which is confluence of material science, surface science and applied physics and has became an identifiable unified discipline of scientific end over. The studies on the thin film formation are being pursued in increasingly on account of its proven and potential applications in variety of semiconductor devices.Twentieth Century has experienced a tremendous development of solid state physics; both in terms of understanding and applications. The birth of quantum theory contributed a great deal to our current understanding of the entire gamut of interesting properties exhibited by bulk solids, surfaces and interfaces. This turn has helped in the diverse applications of solid state materials, giving birth to full fledged area, which have became new fields in their own right, such as materials science, solid state electronics, nano materials, quasi crystals, etc.
