From: Silicene oxides: formation, structures and electronic properties

Band structures and density of states (DOS) of (a) silicene and a silicene oxide with (b) Oqb, (c) Odb, (d)
, (e)
, (f) OHtl, (g) OHul, (h) OHblor (i) OHal.
Γ, K, M are special points in the first Brillouin zone of a cubic crystal. Γ, X, S are special points in the first Brillouin zone of a hexagonal crystal. Energy is shifted so that the Fermi level is 0 eV (the horizontal dashed line). Conduction bands, valance bands, deep energy levels and DOS are indicated by red, blue, green and pink lines, respectively.
