This volume provides a fresh and unique teaching tool. Over the last decade device performances are driven by new materials, scaling, heterostructures and new device concepts. Semiconductor devices have mostly relied on Si but increasingly GaAs, InGaAs and heterostructures made from Si/SiGe, GaAs/AlGaAs etc have become important. Over the last few years one of the most exciting new entries has been the nitride based heterostructures. New physics based on polar charges and polar interfaces has become important as a result of the nitrides. Nitride based devices are now used for high power applications and in lighting and display applications. For students to be able to participate in this exciting arena, a lot of physics, device concepts, heterostructure concepts and materials properties need to be understood. It is important to have a textbook that teaches students and practicing engineers about all these areas in a coherent manner.

Semiconductor Device Physics and Design teaches readers how to approach device design from the point of view of someone who wants to improve devices and can see the opportunity and challenges. It begins with coverage of basic physics concepts, including the physics behind polar heterostructures and strained heterostructures. The book then details the important devices ranging from p-n diodes to bipolar and field effect devices. By relating device design to device performance and then relating device needs to system use the student can see how device design works in the real world.
