Abstract: | Using the tight-binding model approximation, this paper investigates
theoretically spin-dependent quantum transport through an
Aharonov--Bohm (AB) interferometer. An external magnetic field is
applied to produce the spin-polarization and spin current. The AB
interferometer, acting as a spin splitter, separates the opposite
spin polarization current. By adjusting the energy and the direction
of the magnetic field, large spin-polarized current can be obtained. |
