To Study About the Synthesis and Characterization of ZNS Thin Films
Thin films are two-dimensional products, as there is no length and breadth. There are limits, but its thickness is small. Films with thicknesses ranging from fractions of nanometers to many micrometres are commonly said to be thin films. Thin films of a material have different properties than the bulk shape of a material, and are used in various applications, such as decorations, coatings for corrosion resistance, photovoltaics and batteries. There are substantially different properties of material deposited in thin film form based on its bulk shape. It is therefore important to research the various physico-chemical properties of the deposited material in order to use a material in thin film form for a particular application. The main parameters that determine whether or not the deposited material is appropriate for a specific application are the crystal structure, microstructure, element composition, along with its optical response, such as absorption and transmittance for a given wavelength range, etc. Therefore in order to ensure the consistency of a thin film material, its structural, morphological, compositional and optical properties must be analyzed. Using various techniques of characterization, these properties of deposited thin films can be studied. The following sections deal with various characterization techniques used for ZnS thin film analysis.
