Abstract

Analytical and numerical solutions are two basic tools in the study of photothermal interactions problems in semiconductor medium. This paper is devoted to a study of the photothermal interaction in semiconductor media in the context of the coupled photo-thermal theory. The governing relations are expressed in Laplace transforms domain and solved in the domain by the eigenvalue scheme. The numerical solution is obtained by using the implicit finite difference method (IFDM), the studied fields are obtained numerically and presented graphically. A comparison between the numerical solutions and the analytical solution are obtained. It is found that the implicit finite difference method (IFDM) is applicable, simple and efficient for such problems.
