Straightforward Probing of Polarization and Spin-Resolved Transmission through Potential Barriers in Silicene

Figure 2

(Color online) (a) contour plot of the transmission through a single barrier for spin-up electrons. The width and height of the barrier are  nm and  meV, respectively, the field  meV/nm, and  m/s. Panels (b), (c), and (d) show the region delimited by and  meV and correspond, respectively, to , , and  meV/nm.
