Fig. 1From: Structural and electronic properties of two-dimensional stanene and graphene heterostructureTop and side views of the heterostructure of \( \mathrm{S}\mathrm{n}(3)/\mathrm{G}\left(\sqrt{31}\right) \) (a heterostructure consisting of 3 × 3 stanene unit cell and \( \sqrt{31}\times \sqrt{31} \) graphene unit cell). Yellow, red, and gray spheres represent Sn-top, Sn-bottom, and C atoms, respectively. Δ and D represent the buckling height of stanene and interlayer distance between the substrate graphene and bottom Sn layer, respectively. The black arrows represent the lattice vector \( {\overrightarrow{a}}_{\mathrm{Sn}}\;\mathrm{and}\;{\overrightarrow{a}}_{\mathrm{G}} \) and of the unit cell of stanene and grapheneBack to article page
