Simulation of a resonant tunneling diode using an entropic quantum drift-diffusion model

摘要

We present an entropic Quantum Drift Diffusion model (eQDD). Some links between this model and other existing models are exhibited, especially with the Classical Drift-Diffusion (CDD) model, the Density Gradient (DG) model and the Schroedinger-Poisson model (SP). Numerical results show that the model captures important features concerning the modeling of a resonant tunneling diode. To finish, some comparisons between the models stated above are realized.
