<b>Observation of the track of a misfit dislocation in ordered Ga_0.5In_0.5P</b>

Abstract

Abstract We have found that a misfit dislocation which moves within a slightly strained layer of Ga0·5ln0·5P with atomic ordering on {1T1} planes leaves an observable track in the form of an antiphase domain boundary. Here we describe our observations and discuss the possibility of using this material as a model system for the investigation of strain relaxation mechanisms.
