Abstract

The dynamical behavior of the charge in quantum wells is studied. We obtain the tunneling time as function of geometric parameters. Since at low carrier density the intraband relaxation time is determined by LO-phonon-carrier scattering, we calculate, as a function of several parameters, the energy corrections and the scattering rates within each band, this is done by using a many body perturbative formalism, considering both screened and unscreened potentials. We compare results for GaAs and CdTe double quantum wells.
