This book includes an over view, applications, thin film growth, deposition techniques and fabrication of ZnTe films using successive ionic layer adsorption and reaction process (SILAR) method. Applications of thin films are discussed in brief. Growing thin films go through several distinct stages, each affecting the resulting film microstructure and hence its physical properties in some, sometimes not reversible, ways; discussed in this book. As the growth of these materials in different forms depends on various growth conditions, it is essential to know about the chemical content of these grown materials, particularly, molar concentration, pH level etc. are a strong function of chemical methods like SILAR. Thus a brief review of different techniques used for deposition of ZnTe thin films are presented here and finally a selection of suitable method for the present work is justified.
