Electron tunneling in an asymmetry heterostructure under the influence of both dresselhaus and rashba spin–orbit terms

The problem of spin dependent electron transmission through an asymmetric InAs/GaSb/InAs well is studied theoretically in order to investigate the output transmission current polarization at a zero magnetic field. Transparency of electron transmission is calculated as a function of electron energ...
