Table 1 Structural properties of the substrate-supported bilayer \(\beta _{12}\) borophenes: lattice constants (a and b), interlayer distance (d), substrate-overlayer distance (l), substrate adhesion energy (\(E_{ad}\)), number of covalent bonds per unit cell (\(n_B\)), and density of electrons donated from the substrate (\(\rho _d\)).
