Abstract Scope |
Materials with small dimensions and high surface-to-volume ratios are subject to shape changes driven by surface energy minimization. A common example is the break-up of thin films to form islands, solid-state dewetting, which occurs while the material remains solid and at temperatures that decrease with film thickness. Much has been learned about the mechanisms that govern solid-state dewetting of both polycrystalline and single crystal materials. Crystalline anisotropy has been shown to strongly affect morphological stability, and new methods for accounting for anisotropy in modeling of morphological evolution have recently been introduced. Experiments in which solid-state dewetting is templated by film or substrate lithographic patterning have provided application-relevant mechanistic studies of the morphological evolution of films, wires and individual islands. This has also led to development of new methods for producing and controlling the stability of micro- and nano-structures. |
