Abstract
When a spin bias is applied to a two-terminal device, a charge current will be generated. We demonstrate the rectification of such a current by studying spin-dependent transport through a quantum point contact (QPC) modulated by a spin-orbit interaction. When the polarization orientation of the spin bias (which is the spin-quantization axis) is along the transverse direction of the QPC, the two spin-conserved transmissions show a distinct variation with the incident energy. As a result, the charge current can turn from zero to a remarkable value by switching the spin bias from one lead to the other lead.
