Development of band patterns in surface films: A simple theory
Semiconductor technology often employs thin films deposited on crystal surfaces, and in some cases these films can self-organize into band, ring or spiral patterns during annealing. A simple theory is proposed which predicts the stability or instability of such films and, in the case of instability, the band spacing, which depends upon bulk, surface and interfacial free energies. This information could be of use in self-assembly techniques. In some cases, bands condense into particle arrays...[Show more]
