Abstract
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.
