摘要：

The behavior of steps on the basal surface of alumina under conditions of evaporative mass transport has been investigated. Steps on a clean surface of alumina tend to be uniformly spaced indicating a repulsive interaction between the steps. The presence of foreign particles causes step bunching that leads to the formation of a new facet. The lower energy of the macrofacet may provide a driving force for the bunching process.
