Abstract

Modulations of the quantum spin pumping were investigated in magnetic field effect semiconductors. With Floquet technology, theoretical realizations of the semiconductor pump are shown clear and feasible. Due to perpendicular magnetic fields in a semiconductor with two types of spin-orbit couplings (SOCs), spin polarized pumpings can be produced. Moreover, pure spin currents are enhanced by proper modulations of the magnetic fields and SOCs, and thus a good quantum spin pumping can be realized.

Keywords
