Abstract

Transitions in the distribution of atomic steps on a Ni surface vicinal to (111) have been observed using LEED. The observations indicate a tendency for steps to cluster at low temperature and to disperse at high temperature. The transitions can be reversed on temperature cycling but with some hysteresis which may be due either to the nature of the transition or to kinetic effects. Carbon, oxygen, and sulphur affect the transition temperature.
