‘‘A transmission electron microscope study of twin structure in GaAs/GaAs (111)B grown via molecular‐beam epitaxy’’

摘要

A transmission electron microscope study of the twin structure in thin GaAs films grown by molecular‐beam epitaxy on (111)B GaAs reveals the twinned region to be composed of three distinct crystallites which are single‐ and double‐twin variations of the bulk crystal. A three‐dimensional structure of the twin region involving variants of these crystallites, as required by the threefold symmetry of the (111)B plane, is proposed.
