Mass transport via surface diffusion is very efficient at small scales. Thin solid films on crystal surfaces, therefore behave in an unexpected way. For example, it can dewet and form droplets just as a water film on glass. Such a process is, like electromigration induced instabilities, a major source of failure of nanostructured devices. We study the basic laws which govern its evolution.
