Solid-state wetting at the nanoscale

The aim of this lecture is to provide an overview on solid-state wetting, starting from basic concepts, and introducing the useful mathematical paraphernalia. We review and discuss the similarities and the differences between liquid-state and solid-state wetting. Then, we show how wetting concepts provide tools to understand the morphology and stability of solid-state thin films and nano-islands. (C) 2016 Elsevier Ltd. All rights reserved.
