Thin film science has received tremendous attention in last five decades especially after the word war II, because of numerous and wide spread applications of thin films in diverse fields such as electronics industries, microelectronics and hybrid circuits, optical devices, sensors, superconductivity and recently high memory computer elements etc. This book entitled "Study of Transport Properties of Lead Selenide Thin Films" gives the variation of Resistivity and Thermo electric power with temperature confirm a semiconducting nature of films. An attempt has been made to evaluate the fermi energy and absorption coefficient as a function of thickness.
