Pb(Zr0.52,Ti0.48)O3 thin-films with various thicknesses were prepared on releasable Pt/SiO2/Si substrates. The adhesion force between Pt and SiO2 was estimated, mainly in the viewpoint of the diffusion of Pb, in X-ray photoelectron spectroscopy (XPS) and tensile test for the clarification of the bonding properties of the nano-transfer method. The adhesion strength of Pt to SiO2 has an inverse linear relationship with the thickness of Pt. On the other hand the adhesion strength of the samples, that were crystallized with different number of layers, were shown to be in the same region of 2–4 MPa as in case of PZT with over 250 nm in thickness. These results indicate that the origin of the bonding is the diffusion of Pb in the film and that the bonding strength is connected with the earlier stage of crystallization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
