About the BookAbout the AuthorTable of Contents

Physics of Semiconductor Devices is a comprehensive, up-to-date text providing a lucid perspective of the important concepts and applications of semiconductor devices. The book emphasises a logical development of the subject and maintains a rigour in the analytical discussions. A description of the quantum mechanical tunnel effect on the principles of quantum measurement and observations is also presented, along with a discussion of its application in the analysis of I-V characteristics of tunnel devices. In this revised edition, the basic outline of the book and its underlying philosophy remain unchanged. The discussions on “quantum mechanical tunnelling” have been updated. Most of the problems in the first edition have been retained and a large number of problems have been added both as solved examples and as unsolved exercises.
