Engineering Epitaxial Silicene on Functional Substrates for Nanotechnology

Figure 5

Silicene on sapphire. A theoretical model of the weakly interacting silicene on Al2O3(0001) substrate (a); its electronic band structure (b); and the optical conductivity of the silicon nanosheets of variable thickness from 0.5, i.e., silicene, to 7 nm as schematically depicted in the inset (c).
