Query: SOS model of overlayer induced faceting   A solid-on-solid model is proposed to describe faceting of bcc(111) metal
surface induced by a metal overlayer. It is shown that the first order phase
transition occurs between faceted {211} or {110} and disordered phases. The
ordered phases consist of large 3-sided pyramids with {211} facets or {110}
facets. It is shown that the high-temperature disordered phase has not planar
bcc(111) structure but faceted disordered structure. Hysteresis effects were
observed when the system was warmed above the transition temperature and then
cooled down. Temperature dependence of LEED patterns for faceted and disordered
phase are calculated in kinematic approximation.
