摘要

非平衡格林函数(NEGF)方法能够预测纳米器件的相干和非相干效应。为了处理非相干散射，载流子产生和重组在计算上是非常昂贵的。在这项工作中，扩展了数值上有效的Buttiker-probe模型，以涵盖复合和生成效应以及各种非相干散射过程。以量子阱III-N发光二极管和反双极性二维材料异质结为例，证明了新方法预测纳米器件的能力。

Nonequilibrium Green’s function method: Büttiker probes for carrier generation and recombination

The non-equilibrium Green function (NEGF) method is capable of nanodevice performance predictions including coherent and incoherent effects. To treat incoherent scattering, carrier generation and recombination is computationally very expensive. In this work, the numerically efficient Buttiker-probe model is expanded to cover recombination and generation effects in addition to various incoherent scattering processes. The capability of the new method to predict nanodevices is exemplified with quantum well III-N light-emitting diodes and anti-ambipolar 2D material hetero junctions.
