4. Properties and Characterization of Thin Films
... This metod is mostly used in PVD processes for the production of single layer and multiplayer coatings for optical applications. It measures the optical thickeness nd so that it allows for a compensation of changes in the refractive index n by corresponding changes of the film thickness d. With a ph ...

Mechanisms and energetics of surface reactions at the copper
... been shown that a Cu[100] surface becomes unstable and reconstructs when the oxygen coverage is higher than 1/3 ML (Fujita et al. 1996). It is thus reasonable to assume that even on an oxidized copper surface there is a significant surface area on which copper atoms are exposed and able to adsorb wa ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
