摘要:
We propose a new scheme of spin filtering employing ballistic nanojunctions patterned in a two dimensional electron gas (2DEG). Our proposal is essentially based on the spin-orbit (SO) interaction generated by a lateral confining potential (beta-SO coupling ). We demonstrate that the flow of a longitudinal unpolarized current through a ballistic T and X junction with this spin-orbit coupling will induce a spin accumulation which has opposite signs for the two lateral probes and is, therefore, the principal observable signature of the spin Hall effect in these devices.
