Surface Structure and Growth of Crystalline Materials.
Abstract
Computer simulation methods have been used to study spiral crystal growth from multiple dislocation edges. The results showed that after the spiral arms had all interacted once growth proceeded in agreement with the Burton-Cabrera-Frank continuum theory. For small Frank-Read dislocations the existence of a nucleation barrier was shown. Computer simulation studies of simple models of magnetic (binary alloy) lattices with exposed surfaces were also carried out. Surface order-disorder and order-order transitions were studied as a function coupling both below and above the bulk transition surface. (Author)
