量子阱中电子扩展态态密度与分离求和向连续积分过渡的问题

The State Density of Electron Extended States in Quantum Well and the problem of Discretc Sum Transform of continuous Integral

本文分析了现有文献中关于量子阱中电子扩展态态密度计算的几种结果的差异性和原因，从而论证了我们采用的格林函数方法所得结果的正确性．

In this paper we have discussed the reasons of the discrepancy of several calculational results in literature availabl about the state density of electron extended states in quantum well,and have demonstrated that our results calculated by green function method is correct.
