Description
It is important to note that semiconductors are quite different from either metals or insulators, and their importance lies in the base that they provide to a massive microelectronics and optics community and industry. This book, written for graduate students, describes how quantum mechanics gives semiconductors their unique properties that enabled the microelectronics revolution and focusses on the electronic band structure, lattice dynamics and electron–phonon interactions in semiconductors; properties that make semiconductors the foundation of the modern microelectronics industry.About Editors
