Asymmetric Silver to Oxide Adhesion in Multilayers Deposited on Glass by Sputtering

摘要

We have developed a wedge-loaded double-cantilever beam adhesion measurementset-up for thin films deposited on glass by sputtering. The test is describedin details. Results on the Glass/sublayer/Ag/ZnO multilayer provide evidencethat \SnOd or \TiOd perform better than ZnO as a sublayer. Then however,rupture within the multilayer shifts to the upper Ag/ZnO interface. The latteris shown to be tougher than the lower ZnO/Ag interface, an asymmetry due tonon-equilibrium interfacial structures.
