Book Description

Although there is a good deal of research concerning semiconductor impurities available, most publications on the subject are very specialized and very theoretical. Until now, the field lacked a text that described the current experimental data, applications, and theory concerning impurities in semiconductor physics.

Impurities in Semiconductors: Solubility, Migration and Interactions explores the behavior of impurity atoms in semiconductors, integrating experimental data with theoretical interpretation. It presents the current literature on the state and behavior of impurities in semiconductors. The author explains the basic physics of hydrogen-like impurities to help you understand the properties imparted by these impurities. He also analyzes the macroscopic and microscopic mechanisms of the solubility, and migration of impurities and defects in the crystal lattice. In addition, the book presents a systematic analysis of different effects resulting from the interactions between impurities and other defects in the crystal lattices.

This book brings to light work done in the former Soviet Union and highlights several impurities that have potential, but have not yet found widespread application. As such, it will be an invaluable reference for those working in different fields involving the use of electronic materials.
