Semiconductor Devices - Tutorial Guides in Electronic Engineering

This book presents semiconductor devices in a clear and concise manlier, dealing with the material encountered in the first and second years of an undergraduate or Higher National Diploma programme in electronics, electrical engineering or physics. It provides an ideal introduction firstly to the fundamental theoretical principles underlying the operation of semiconductor devices and, secondly, to their simple and effective mathematical modelling. There are also extensive references to circuit simulation software.;In this enlarged second edition, the opportunity has been taken to show how the concept of electron energy bands can be used to introduce the physical processes in semiconductor devices. Explanations are given of a wider range of device characteristics in circuit applications and how these characteristics can be modelled by equivalent circuits. As well as a full update of the original text, the new edition contains: new material on the band model of an junction; new material on the band gap diode; and expanded treatment of JFETs to complement the existing material on MOSFETs.
