چکیده انگلیسی
In this paper we propose a model for computing the transmission coefficient and the dwell time of the electron tunneling through a multiple quantum well structure with Rashba spin-orbit interaction and with an external and constant electric field, using the transfer matrix formalism with piecewise constant potentials. The results indicate a difference between the transmission coefficients and the dwell times for spin-up and spin-down orientations. This difference can be modified by varying the electric field and the number of the barriers and wells, this opening the way to create a spin filtering in the time domain.
