This work deals with the physics, operating principles and characteristics of the important quantum well devices, namely, the High Electron Mobility Transistor (HEMT), Resonant Tunneling Diode (RTD), Quantum Well Laser (QWL), Quantum Well Infrared Photodetector (QWIP), Modulator and Switch. The basic physical concepts on which these devices are based are discussed in detail with necessary diagrams and mathematical derivations. The growth of heterostructures, theories and experiments on band offset, theories and experimental results on electron states, optical interaction phenomena, and electron transport are discussed as the background material. Practical aspects and up-to-date developments and applications of the devices are also covered. This book should be of interest to researchers and specialists in the field of Solid State Technology and Optics and Optoelectronics. It can also serve as a textbook for graduate students and new entrants in the exciting field of quantum electronics.
