About Electrical Properties of Solids
Electrical properties of solids depend on their band structure, charge carriers and conductivity. The topic compares conductors, insulators and semiconductors, relates resistivity to temperature, and covers intrinsic and extrinsic semiconductors, donor and acceptor impurities, electron and hole conduction, and the formation of p-type and n-type materials.
