Abstract

We have developed a wedge-loaded double-cantilever beam adhesion measurement set-up for thin films deposited on glass by magnetron sputtering. Results on the Glass/ZnO/Ag/ZnO multilayer evidence that the upper Ag/ZnO interface is tougher than the lower ZnO/Ag interface. This asymmetry in the adhesion energy between identical materials is not expected from first principles. It results from different non-equilibrium interfacial structures.
