摘要

在这项工作中，我们使用非平衡格林函数(Non-Equilibrium Greens Function, NEGF)方法来说明通过能量滤波可以实现σS2改进的设计细节。我们进一步证明了设计参数的变化，最重要的是势垒高度的变化是一个强大的有害机制，它可以带走大部分能量过滤的好处。

Thermoelectric power factor optimization in nanocomposites by energy filtering using NEGF

InIn this work, we use the Non-Equilibrium Greens Function (NEGF) method to illustrate the design details under which improvements in σS2 can be achieved by energy filtering. We further demonstrate that variation of the design parameters, and most importantly in the barrier heights is a strong detrimental mechanism which can take away most of the energy filtering benefits.
