Paper Abstract

Water-penetration-induced morphological changes in Y2O3 monolayer coatings were studied by means of atomic force microscopy. In a standard laboratory environment, there appears a long-term growth kinetics for these morphological modifications. On a time scale of months, thin films undergo solid-state phase transformations converting the nano-scale columnar, porous film structure to micron-scaled crystallites and islands. We compare these phenomenological long-term observations with accelerated testing results using either a 100% relative humidity environment or artificial seeding of film surfaces by distilled H2O microdroplets.
