摘要：
The formation of a spinel phase was observed after chromium deposition on a ZnO single crystal substrate and subsequent annealing. The structure of the spinel and its epitaxial relationship with the substrate were investigated by using X-ray photoelectron diffraction. Experimental data are discussed on the basis of a single scattering cluster-spherical wave model calculation. The presence of octahedrally coordinated Zn was ruled out and the deviation from stoichiometry is attributed to amorphous ZnO patches in the spinel matrix. (C) 1997 Elsevier Science B.V.
