With its strong pedagogy, superior readability and thorough examination of the physics of semiconductor material, Semiconductor Physics and Devices, Fourth Edition provides a basis for understanding the characteristics, operation and limitations of semiconductor devices. Neamen's Semiconductor Physics and Devices deals with electrical properties and characteristics of semiconductor materials and devices. This book aims to combine quantum mechanics, the quantum theory of solids, semiconductor material physics and semiconductor device physics clearly and understandably. Salient Features: 1) Extensive Coverage of Physics and Quantum Theory in Chapters 2 and 3, preparing students for a deeper understanding of developing new semiconductor devices. 2) Comprehensive Coverage of Semiconductor Devices is presented from Chapter 7 onward. Each chapter treats a different device family. The organization of this book is flexible to accommodate other preferences and teaching styles. 3) Design Examples and homework problems help students grasp more practical and open-ended problem-solving methods. The examples contain all the details of the analysis or design, so the reader does not have to fill in the missing steps. These design-oriented examples are marked with an icon. 4) Enhanced Learning System with the inclusion of "Test Your Understanding Exercises" added after each example, and learning objectives are included before each example as well. A preview section opens each chapter and links the current chapter's goals to those of earlier material.
