A hyperbolic two-temperature photo-thermal interactions in a semiconductor material

Abstract

This work is concerned with the study of the thermodynamic temperature, conductive temperature, the carrier density, displacement and stress in a semi-infinite semiconductor medium during the photo-thermal process. The medium is considered to be a semiconducting media with an isotropic and homogeneous. Also, the thermal and elastic properties have been considered without neglecting the coupling between the thermoelastic and the plasma waves. The techniques of Laplace transforms are used to get the analytical solutions of the problem in the transformed domain by the eigenvalues method and the inversions of Laplace transformations have been carried numerically. The results are graphically represented to show the effects of the two-temperature parameter.
