Configuration of Antiphase Domains in One-Dimensional Long Period Superstructural Alloys

Abstract

ABSTRACTThe configuration of antiphase domains in a one-dimensional long period superstructure (LPS) was examined theoretically. As LPS is composed of two kinds of antiphase domains, the domain-arrangement is described by f(n) , where f(n) is the existence probability of n which is the number of the majority domains between two minority ones. The equations for f(n) were derived using statistical approaches or thermodynamical ones, and f(n) predicted from the equations were compared with those obtained experimentally.
