24. We have performed the calculations for the silicene on Ag(111) with the 4 × 4 periodicity and for the silicene/H-covered Si(111) (see text) with the generalized gradient approximation [Perdew et al.: Phys. Rev. Lett. 77 (1996) 3865].
25. with the van-der-Waals-corrected functionals [optB86b-vdW as in Klimes et al.: Phys. Rev. B 83 (2011) 195131] as is implemented in VASP.24) The obtained structures are same with the LDA structures with the difference of several % and the energy bands are essentially identical to the LDA bands. The mixed (π*) states appear at 1.0 eV below EF in the optB86b-vdW for the silicene on the 4×4 Ag(111).

29. STM images are obtained by the following scheme: J. Tersoff and D. R. Hamann: Phys. Rev. B 31 (1985) 805. The images are insensitive to the bias voltage.

31. 2 [Z. Ni et al.: Nano Lett. 12 (2012) 113]. In this work, we focus on the stability of silicene on multilayer h-BN substrate with AÁ stacking. We have considered the effect of lattice mismatching as well as adsorption configurations of silicene on h-BN. The results shown in the text are obtained based on the most stable configuration with the lattice mismatch of 0.64%.
32. We have also examined possibilities that a Si atom in the silicene layer is incorporated into the subsurface layer and found that the incorporation is endothermic.
