Optimized geometric atomic configurations and structural parameters of H@silicene. (a) Top view with the rhombus marked in black showing the supercell. Bravais lattice vectors of a unit cell are given with a 1 = a 2 = a = 3.899 Å. (b) Side view. The average bond length d 1 (Å) between Si and H atoms, d 2 (Å) between Si and Si atoms, and buckled height ΔZ(Å) between Si and Si layers. The yellow and white balls stand for Si and H atoms, respectively. (c) Band structures of H@silicene. Arrow denotes the spin-polarized direction. The top of the valence band is set to zero.
