The differential equations and boundary conditions describing the behavior of a finitely deformable, polarizable and magnetizable heat conducting and electrically semiconducting continuum in interaction with the electromagnetic field are derived by means of a systematic application of the laws of continuum physics to a well-defined macroscopic model. The model consists of five suitably defined interpenetrating continua. The relative displacement of the bound electronic continuum with respect to the lattice continuum produces electrical polarization, and electrical conduction results from the motion of the charged free electronic and hole fluids. Since partial pressures are taken to act in the conducting fluids, semiconduction boundary conditions arise, which have not appeared previously. The resulting rather cumbersome system of equations is reduced to that for the quasi-static electric field and static homogeneous magnetic field. A analysis of the propagation of both plane and surface waves in piezoelectric semiconductors subject to a static biasing electric field is presented.
