摘要
对泊松方程有效地进行数值计算是PN结电荷分布与静电势之间关系分析的一个基本问题。介绍了一种利用MATLAB和打靶法求解平面PN结一维泊松方程的简捷方法。该方法的计算结果与有限差分法吻合得很好,并具有编程简单、使用方便的特点。
The effective numerical calculation of Poisson's equation is a basic issue for the analysis of the relationship between the charge distribution and electrostatic potential in a PN junction. A simple method for solving the one-dimensional Poisson's equation of a planar PN junction via MATLAB-based shooting is presented. The calculation result of the method is in good agreement with that of the finite difference method. This method has the features of simple programming and convenient use.
