摘要

在III-V装置的模拟中，当将漂移扩散和流体动力输运与负微分迁移率模型结合使用时，经常观察到收敛问题。本文解释了这两种传输模型的问题原因。此外，还讨论了实现收敛的已知措施及其含义。

On the use of Drift-Diffusion and Hydrodynamic Transport Models for Simulating the Negative Differential Mobility Effect

In simulations of III-V devices, convergence issues are often observed when using drift-diffusion and hydrodynamic transport in conjunction with the negative differential mobility model. This paper explains the cause of the problem for each of the two transport models. Furthermore, known measures for achieving convergence and their implications are discussed.
