We study the diffusion approximation of a Boltzmann-Poisson system dealing with Fermi-Dirac statistics in the presence of an extra external oscillating electrostatic potential. The relative entropy disspation and the two-scale Young measures are used to prove a two-scale strong convergence leading to a nonlinear Drift-diffusion with a effective potential and coupled to Poisson equation.
