Research output: Contribution to journalArticle


This paper deals with the diffusion approximation of a semiconductor Boltzmann- Poisson system. The statistics of collisions we are considering here, is the Fermi- Dirac operator with the Pauli exclusion term and without the detailed balance principle. Our study generalizes, the result of Goudon and Mellet [11], to the multi- dimensional case.
