“…Similarly three component numerical simulations have been successfully applied to inorganic systems. 25,26 As in the two component situation the calculations are based on the elastodynamic Green's function method, it is thus necessary to count on reliable values of the densities and elastic constant tensors of the constituting materials (Au, graphene oxide and glass).…”

“…40 The displacement of the Bragg peak toward lower angle was already observed in sputtered ZnO films of similar thickness prepared under different conditions, as well as in Zn 0.95 Mn 0.05 O films. 41 These studies indicate the presence of tensile stresses in the direction perpendicular to the substrate in the as-grown films, both ZnO and Zn 0.95 Mn 0.05 O. Annealing in oxygen atmosphere improves crystallinity and leads to stress relaxation, shifting the (002) peak position to 34.4 , the stress-free powder value. As-deposited ZnO films appear elastic enough to support large stresses.…”

Multilayered films of Au/ZnO were prepared by physical vapor deposition. Varying the Au thickness, t Au , and the number of bilayers, n, allowed us to investigate the role of these parameters on the sample structural and electronic properties. X-ray diffraction, X-ray absorption spectroscopy, grazing incidence small angle X-ray scattering and transmission electron microscopy experiments, have been combined to UV-visible and infrared spectroscopy to characterize the multilayers in the as-prepared state and after annealing. In the as-prepared state, the strong Au and ZnO lattice interaction leads to ZnO epitaxy on Au. Gold appears either as continuous layers or in form of nanoparticles. ZnO experiences a structural transformation from wurztite to rock salt monitored by the Au morphology. Annealing at 500 C destroys the lattice matching. The electronic and optical properties of the systems are understood in line with the Au morphology and ZnO structural state.
