Analytical solutions of photothermal wave in semiconductor materials

In the present study, a theoretical model that interconnects plasma waves, thermal dynamics, and elastic vibrations has been applied to examine the propagations of waves in semiconductors as a result of photo-thermal effects. A study was conducted on a semiconducting material that is both isotropic and elastic, displaying uniform thermoelastic properties. This research looked into how plasma, thermal, and elastic waves, which are produced by a sharply focused laser beams with modulated intensity, interact within the material. Using Laplace transform methods, the analytical solutions obtained through the eigenvalues approach in the transformed domains were observed. To do the numerical calculations, a semiconductor resembling silicon was used.
