Synthesis Structural Electrical Optical and Thermoelectrical

Thin film science has received tremendous attention in last five-six decades because of numerous and widespread applications of thin films in diverse fields such as electronic industries and hybrid circuits optical devices sensors superconductivity and recently high memory computer elements etc. The II – VI and IV-VI chalcogenide compounds are of prime importance from the point of view of device applications in various fields. They have been considered as promising materials for technological applications in the field of IR devices diodes lasers thermo photovoltaic converts nanowires solar cell electroluminescence. Lead chalcogenides have narrow energy gap and are semiconductors having structural and electronic properties like high carrier mobility high dielectric constants an attempt has been made to study on end compound of Pb1-xInxSe that is PbSe and InSe films as well as middle compounds. The Fermi energy electrical energy band gap mobility carrier concentration thermo electric properties scattering parameters optical direct and indirect band gap absorption coefficient extinction coefficient were evaluated.
