β¦ Synopsis
The electronic structure and bonding configuration at the interface between cubic (zincblende) BN and XC (X = Si, Ge, Sn) are studied using the full-potential linearized augmented plane wave approach within the density functional theory in the local density approximation. The (001) superlattice of (BN) n /(XC) n is used to study the interface. The calculated results show that the preferred bonding configuration is X-N and C-B for the (001) BN/XC interface. The formation energy of the interface is studied as a function of thickness of the superlattice. The origin of the bonding formation as well as the electronic properties are also investigated.
