Physics of semiconductors and their heterostructures / Jasprit Singh

Information About

i) electronic properties of semiconductors including the concept of effective masses, donors, acceptors, excitons etc; ii) modification of electronic properties by using heterostructure concepts, i.e., via reduced dimensionality, confinement and built in strain; iii) properties of electronic materials as reflected in electronic transport and optical properties. These areas will provide students an intimate knowledge of the material properties on which solid state electronic devices such as transistors, Gunn diodes, lasers, detectors, optical memories, etc., are based. Emphasis are placed on not only conceptual understanding but quantitative understanding of a variety of semiconductors and their combinations via numerical calculations. This book is written for graduate students who have had a basic quantum mechanics course. A generous number of appendices have been included so that gaps that may appear in the student's knowledge can be overcome. The emphasis on actual numbers is also reflected in two appendices where explicit numbers are evaluated for various physical processes.
