ABSTRACT: 半导体是近代发现的一种新型材料，其导电性能介于导体与绝缘体之间，并且导电性也会随温度变化，是制作电子器件的重要材料，因此半导体器件问题的数值模拟也越来越重要。本文主要研究用Matlab中PDE工具箱对瞬态半导体器件的数学模型进行求解，通过数值模拟得出其电子位势、电子浓度和温度分布数值解，并通过图像得到了半导体的物理变化情况，充分展现了PDE工具箱在求解过程中的操作简单、计算快等优点。

Semiconductor is a new kind of material discovered recently. Its conductivity is between conductor and insulator, and its conductivity changes with temperature. It is an important material for making electronic devices. Therefore, numerical simulation of semiconductor device problems is becoming more and more important. The mathematical models of semiconductor devices are considered. Matlab PDE toolbox can solve a series of problems semiconductor device simulation. Numerical simulation of the electric potential, electron concentration and the temperature distribution in the image can verify the semiconductor physical change in the situation. So the PDE toolbox has the advantages of simple operation and fast computation.
