Fig. 3From: Structural and electronic properties of two-dimensional stanene and graphene heterostructureInterlayer binding energy per Sn atom of the bilayer \( \mathrm{S}\mathrm{n}\left(\sqrt{7}\right)/\mathrm{G}(5) \) as a function of interlayer spacing. Results using different exchange-correlation functionals are shown. See text for the geometry and the binding energy definitionBack to article page
