Electric Barrier

We theoretically present the spin-dependent electron transport in a two-dimensional electron gas (2DEG) with finite width modulated by magnetic–electric barriers. It is found that the transmission probability and the spin polarization are strongly dependent on the height of the electric barrier, the energy of the incident electron, the distance between the two magnetic fields, and the width of the 2DEG. These may be useful for making the practical devices.
