摘要

There are many models for semiconductors. They include the quantum, kinetic and fluid level formulation. We consider the electro-hydrodynamic equations (also called energy balanced equations or extended drift diffusion models) which are intented to take into account high field effects. They are obtained by closing the moments equations derived from the Boltzmann equation with a phenomenological assumption on the distribution function. The distribution is assumed to be isotropic around its mean velocity (see, for instance, Blotekjaer [Bo], Odeh, Gnudi and Rudan [OGR]). Then, fluid equations are obtained with source terms modelling relaxation processes and electric fields effects coupled with the Poisson equation. Some recent numerical work include papers Chen, Z. et al. [CC] in two space dimensions.
