Figure 1

(a) and (b) are the top view and side view for the spin-polarized electron density distribution of the silicene bilayer, respectively. The spin-up density is in red while the spin-down density is in green, and the isosurface is plotted at the value of $0.25\mathrm{electrons}/{\AA }^3$. (c) The calculated DFT electronic band structure for the silicene bilayer with spin polarization (in blue). The two bands near the Fermi level for the non-spin-polarized state are also plotted (in black) for direct comparison.
