Studies of ordering on surfaces and in superlattices by molecular beam epitaxy

Molecular beam epitaxy, MBE, was used in two different ways to study ordering on atomic scales. In one application the ordering of close packed planes into various stacking sequences was investigated by periodically alternating growth of Ir and Ru to produce single crystal superlattices. In addition, a novel probe of the kinetics by which a surface of Cu$\sb3$Au re-orders was developed. By growing a disordered layer onto a well ordered surface, the kinetics of ordering in layers of almost arbitrarily small thickness can be studied. By eliminating the need to quench the sample this procedure removes the effects of the re-ordering of the bulk and allows for study at temperatures far below the transition temperature.
