The growth of silver at room temperature on the two polar faces of ZnO (0001) Zn terminated and (0001) O terminated, has been investigated in situ by using grazing incidence x-ray diffraction and grazing incidence small angle x-ray scattering (GISAXS). On both surfaces, silver forms nanoclusters with (111) top facets in hexagon-on-hexagon epitaxy with [101]{sub Ag} parallel [100]{sub ZnO}. Despite the high lattice mismatch in the latter direction (-11%), the Ag islands adopt their bulk…

Band alignment at the interface between evaporated silver films and Zn- or O-terminated polar orientations of ZnO is explored by combining soft and hard x-ray photoemissions on native and
Unstrained islands with interface coincidence sites versus strained islands: X-ray measurements on Ag ∕ ZnO

Microscopic characteristics of the Ag(111)/ZnO(0001) interface present in optical coatings
A first-principles computational method is used to investigate the microscopic properties of the $\mathrm{Ag}(111)∕\mathrm{Zn}\mathrm{O}(0001)$ interface that is often present in optical coatings
Orientation-dependent chemistry and band-bending of Ti on polar ZnO surfaces.
A difference in the activation temperature between the O-terminated (500 K) and Zn-terminate (700 K) surfaces is observed, which is tentatively explained by different electric fields in the space charge layer at ZnO surfaces.
The investigation of Ag/ZnO interface system by first principle: The structural, electronic and optical properties
Abstract Ag/ZnO interfaces have been investigated for both of Zn-termination and O-termination by the first principle based on density functional theory. Our calculations demonstrate that the Ag

Polarity of oxide surfaces and nanostructures
Whenever a compound crystal is cut normal to a randomly chosen direction, there is an overwhelming probability that the resulting surface corresponds to a polar termination and is highly unstable.
