Theory of Semiconductor Junction Devices: A Textbook for Electrical and Electronic Engineers presents the simplified numerical computation of the fundamental electrical equations, specifically Poisson's and the Hall effect equations. This book provides the fundamental theory relevant for the understanding of semiconductor device theory. Comprised of 10 chapters, this book starts with an overview of the application of band theory to the special case of semiconductors, both intrinsic and extrinsic. This text then describes the electrical properties of conductivity, semiconductors, and Hall effect leading to the main topic of p–n junction theory. Other chapters examine the characteristics of the p–n junction in detail as this forms the fundamental element in the majority of semiconductor devices. The final chapter deals with the field effect transistor, which is known as the unipolar transistor. This book is a valuable resource for students of solid state electronics. Electrical and electronic engineers will also find this book useful.
