Abstract

The zinc-terminated, ZnO(0001)-Zn, and the oxygen-terminated, ZnO(0001̄)-O polar surfaces have been studied by low-energy alkali ion scattering. Single scattering analysis shows that both surfaces exhibit a surface structure that is bulk-terminated. No evidence is found for registry shifts at the surface or substantial quantities of point defects such as Zn or O vacancies as may be expected to relieve charge imbalance at the surface. Comparison with the results of computer simulation confirms the bulk-terminated structure, but fails to quantify the interlayer spacing. A less satisfactory agreement between experiment and computer simulation is obtained for the Zn-terminated surface than for the O-terminated surface. It is found that, due to interference of multiple scattering from second and third layers, layer spacings cannot be trivially extracted from single scattering analysis. However, specific scattering conditions are identified for the oxygen-terminated surface, where spacing in the first O-Zn double layer can be obtained. This spacing is found to be nearly identical to the bulk value. Published by Elsevier Science B.V.
