Abstract

In this work, we compare the analytical solutions with the numerical solutions for photothermal interactions in semiconductor medium containing cylindrical cavity. This paper is devoted to a study of the photothermal interactions in semiconductor medium in the context of the coupled photo-thermal model. The basic equations are formulated in the domain of Laplace transform and the eigenvalue scheme are used to get the analytical solutions. The numerical solution is obtained by using the implicit finite difference method (IFDM). A comparison between the analytical solution and the numerical solutions are obtained. It is found that the implicit finite difference method (IFDM) is applicable, simple and efficient for such problems.

用解析和数值方法研究了具有圆柱形腔的半导体介质中的光热相互作用

本文比较了含圆柱形腔半导体介质中光热相互作用的解析解与数值解。本文在耦合光热模型的背景下，对半导体介质中的光热相互作用进行了研究。在拉普拉斯变换域中建立了基本方程，并利用特征值格式得到了解析解。采用隐式有限差分法(IFDM)得到了数值解。对解析解和数值解进行了比较。结果表明，隐式有限差分法(IFDM)是求解此类问题的一种简便有效的方法。
