Abstract

The lattice relaxation of a ZnO single crystal with the (000 1) polar surface terminated by Zn ions was investigated on the basis of DV-Xα calculations. The chemical bonding states of ZnO were evaluated using cluster models of [Zn₁₃O₁₃] for the (000 1) surface and [Zn₁₉O₂₀]^2- for the bulk. From bond overlap populations, it was shown that the covalent bond strength of the surface took a maximal value for the lattice elongation of 0.04 nm, being ascribed to the decrease in the antibonding feature between Zn-3d and O-2p orbitals. The covalent bonding plays an important role in the lattice relaxation of the (000 1) ZnO surface.
