On Purely Macroscopic Theory of Rigid Semiconductors Constructed from Multi-Continuum Model

A complete and systematic derivation of the purely macroscopic theory of rigid semiconductors is given. It is based on a five-continuum model of charged and interpenetrating continua, and the applications of the relevant laws of physics to the continua. The theory is within the quasistatic approximation of electrostatics and is limited to nonmagnetizable materials.
