摘要

Schrödinger方程，或者耦合的Schrödinger和泊松方程，被转换成一个积分方程。从原始方程进行反代，可以使数值修正近似到任意阶，而不需要计算大于1阶的未知函数的导数。典型的应用是在弹道状态下纳米线和纳米管中量子输运的数值分析。

Improving the accuracy of the Schrödinger-Poisson solution in CNWs and CNTs

The Schrödinger equation, or the coupled Schrödinger and Poisson equations, are transformed into an integral equation. Back-substituting from the original equations allows one to approximate the numerical corrections to any order without the need of calculating derivatives of the unknown function of order larger than one. Typical applications are in the numerical analysis of quantum transport in nanowires and nanotubes in the ballistic regime.
