Optically excited plasmaelastic waves in semiconductor plate-coupled plasma and elastic phenomena

Abstract

A system of coupled plasma and elastic waves (the plasmaelastic waves) equations are analyzed. The treatment considers a semiconductor elastic plate with isotropic and homogeneous plasma and elastic properties. The solution of the coupled system of plasma and elastic equations are given for a typical photothermal configuration including the carrier surface and volume recombination processes. The analysis of the plasma density and elastic fields shows that the coupling plasmaelastic effects show the attenuation and disperse phenomena.
