In this paper we are concerned with the study of the relaxation limit of the 3- hydrodynamic model for semiconductors. We prove the convergence of the weak solutions to the Euler-Poisson system toward the solutions to the drift-diffusion system, as the relaxation time tends to zero.

Abstract
In this paper we are concerned with the study of the relaxation limit of the 3- hydrodynamic model for semiconductors. We prove the convergence of the weak solutions to the Euler-Poisson system toward the solutions to the drift-diffusion system, as the relaxation time tends to zero.File in questo prodotto:
