英文摘要	the stoichiometric single- and bilayer zno(0001) have been prepared by reactive deposition of zn on au(111) and studied in detail with x-ray photoelectron spectroscopy, scanning tunneling microscopy, and density functional theory calculations. both single- and bilayer zno(0001) adopt a planar, graphite-like structure similar to freestanding zno(0001) due to the weak van der waals interactions dominating their adhesion with the au(111) substrate. at higher temperature, the single-layer zno(0001) converts gradually to bilayer zno(0001) due to the twice stronger interaction between two zno layers than the interfacial adhesion of zno with au substrate. it is found that cu atoms on the surface of bilayer zno(0001) are mobile with a diffusion barrier of 0.31 ev and likely to agglomerate and form nanosized particles at low coverages; while cu atoms tend to penetrate a single layer of zno(0001) with a barrier of 0.10 ev, resulting in a cu free surface.
