Plasmaelastic and thermoelastic waves in semiconductors

Abstract
The system of coupled plasma and elastic wave (plasmaelastic wave) and thermal and elastic wave (thermoelastic wave) equations are analyzed. The treatment considers a finite semiconductor elastic medium with isotropic and homogeneous thermal and elastic properties. The analysis of the coupled hyperbolic system of plasma, thermal and elastic equations, for a typical photothermal configuration with a semiconductor sample shows, that for various conditions, the different plasmaelastic and thermoelastic wave modes exist.
