半导体漂移-扩散方程速度饱和情形的稳态解

Stationary Solutions of Drift-Diffusion Semiconductor Equations with Velocity Saturates

考虑半导体方程稳态模型的混合边值问题 ,应用Schauder不动点定理证明了逼近解的存在性 ,通过一系列先验估计的获得 ,利用紧致性原理证明了稳态解的存在性 .

In this paper,we consider the stationary solutions to the mixed boundary value problem of the semiconductor equations.By means of approximation method and the priori estimates method,we proved the existence of the stationary solutions for the problem.
