Statistical Thermodynamics of Semiconductor Alloys is the consideration of thermodynamic properties and characteristics of crystalline semiconductor alloys by the methods of statistical thermodynamics. The topics presented in this book make it possible to solve such problems as calculation of a miscibility gap, a spinodal decomposition range, a short-range order, deformations of crystal structure, and description of the order-disorder transitions. Semiconductor alloys, including doped elemental semiconductors are the basic materials of solid-state electronics. Their structural stability and other characteristics are key to determining the reliability and lifetime of devices, making the investigation of stability conditions an important part of semiconductor physics, materials science, and engineering. This book is a guide to predicting and studying the thermodynamic properties and characteristics of the basic materials of solid-state electronics.Includes a complete and detailed consideration of the cluster variation method (CVM)Provides descriptions of spinodal decomposition ranges of crystalline alloys Presents a representation of thermodynamics characteristics and properties as a miscibility gap by using the different approximations of CVMCovers a unique, detailed consideration of the valence force field model with the complete collection of formulas
