Asymmetric Silver to Oxide Adhesion in Multilayers Deposited on Glass by Sputtering
نویسنده
چکیده
We have developed a wedge-loaded double-cantilever beam adhesion measurement set-up for thin films deposited on glass by sputtering. The test is described in details. Results on the Glass/sublayer/Ag/ZnO multilayer provide evidence that SnO2 or TiO2 perform better than ZnO as a sublayer. Then however, rupture within the multilayer shifts to the upper Ag/ZnO interface. The latter is shown to be tougher than the lower ZnO/Ag interface, an asymmetry due to non-equilibrium interfacial structures.

We report on transparent ZnO/Ag/ZnO and ZnO/Ag/ZnO/Ag/ZnO thin-films were deposited on the glass substrate by RF and DC sputtering for ZnO and Ag targets, respectively. The electrical and optical properties of the single and double Low Emissivity coatings were investigated with respect to the deposition time of Ag mid layer. The visible transmittance remains about 65% for single and 45% for...
