(Color online) The schematic configuration for the 2DSL with the electron transport along the x-axis.
The energy spectra along the path , which connects the respective critical points in the BZ (see the inset in (a)) with different : (a) a.u. (1 a.u. = eV.m); (b) a.u.; (c) a.u.; and (d) a.u.
(Color online) (a) and (b) present the spin-dependent conductance against the electron energy with and different : (a) a.u. and (b) a.u. The black solid and red dashed lines correspond to spin-up and spin-down electrons, respectively. (c) and (d) show the spin-dependent conductance vs E with a.u. and different : (c) and (d) . (e) and (f) plot the spin-polarization against E corresponding to (b) and (d), respectively.
(Color online) The spin-dependent electronic charge distributions in the 2DSL. (a), (c), and (e) spin-up electron; (b), (d), and (f) spin-down electron.
