Dinesh C. Agrawal,Rishi Raj +1 more
TLDR
The authors found that thin films of polycrystalline zirconia, deposited on a sapphire substrate become gradually discontinuous when annealed at high temperature, and proposed an approximate criterion for cavity nucleation that depends on the interfacial energies.About:

Periodic mass shedding of a retracting solid film step
TL;DR: In this article, the authors studied the two-dimensional retraction of a semi-infinite, uniform film on a substrate, assuming that the film evolves by capillarity-driven surface diffusion.

Microstructure evolution during dewetting in thin Au films
Claudia M. Müller,Ralph Spolenak +1 more
TL;DR: In this article, electron backscatter diffraction (EBSD) was used to study branched void growth in thin Au films and the holes were found to protrude into the film predominantly at high angle grain boundaries, which can be explained by surface energy minimization of the grains at the void boundaries.
Journal ArticleDOI
Capillary instabilities in solid thin films: Lines
TL;DR: In this article, the authors examined the linear morphological instability of a line of film on a substrate for contact angles between 0 and π and found that mass flows by diffusion along the film surface and that local equilibrium holds.

Temperature-Dependent Morphology Evolution and Surface Plasmon Absorption of Ultrathin Gold Island Films
TL;DR: In this article, the temperature dependence of morphological evolution and the corresponding unique surface plasmon resonance (SPR) properties variation of the ultrathin gold island films (5 nm nominal thickness) upon rapid thermal annealing for 180 s at different temperatures ranging from 100 to 700 °C.

Nucleation of cavities at second phase particles in grain boundaries
TL;DR: In this paper, a kinetic approach is used to explain the nucleation of cavities in grain boundaries at elevated temperature, under the influence of a tensile stress, vacancies cluster together and form cavities.
