Spin transport properties of a Dresselhaus-polygonal quantum ring |
Spin dependent conductances for unpolarized incident electrons: (a) G 0→ m , (b) G m →0, and (c) the polarization for G 0→ m (solid line) and G m →0 (dashed line) in a hexagon versus the value of the wave vector kl with m = 2 and k D l = 0.45 π . |
