Abstract
The primary objective of the ongoing research is to comprehend how waves generated in porous semiconductor elastic media behave during the photothermal process when impacted by laser pulses. In this process, the surface of the semiconductor material is illuminated with a laser pulse. Through the analysis of normal modes, the researchers aim to derive precise expressions for the main physical fields involved in photo-excitation processes. The transportation processes resulting from the excitation of a photo by laser pulses are due to the thermal effects caused by the pulses. To achieve comprehensive solutions for these physical fields, mechanical, thermal, and recombination plasma loads are applied at the surface of the medium. The governing field equations are formulated in non-dimensional forms, incorporating coupled elasticity theory, plasma diffusion equations, void equation, and moving equations. The study focuses on the deformation in two-dimensional (2D) space. The graphical results obtained consider the influences of laser pulses and porosity, and these findings are compared to the behavior of silicon semiconductor material.
