A modern introduction to the physical principles of electronic ceramic materials. Describes theory in structural terms via the language of quantum mechanics and statistical mechanics, bridging the gap between purely theoretical solid-state texts and strictly applied materials science texts. Most of the equations employed are derived from first principles. Each chapter describes the relevant properties of the materials covered, presents applications of the theory, and includes a graded set of problems (some to be done on a computer). Adopts the convention of the American Ceramic Society. Contains tables and figures.
