解M/a-Si势垒区泊松方程

Solving the Poisson's Equation in the M/a-Si Barrier Region

本文证明:(1)对任何形式的、连续的、a-Si隙态密度分布函数,只要我们利用Riemann-Stieltjes积分中值定理,势垒区的泊松方程都可以解析求解.(2)M/a-Si势垒区泊松方程的抛物函数解,是由假定空间电荷区自由载流子耗尽带来的.

In this paper we have proved:(1) For the arbitrary continuous gap state density distribution of a-Si,the Poisson's Equation in the Space charge region is always solvable analytically, if we have adopted the mean-value theorem for Riemann-Stieltjes integral, (R-S inegral).(2) The parabolie funection solution of Poisson's equation in M/a-Si barrier region comes the deplection approxition on the space charge region.
