Using molecular beam epitaxy, Mg₃Sb₂ and Mg₃Bi₂ thin films, as well as Mg₃Sb₂/Mg₃Bi₂ superlattice structures, were fabricated, and their structural and electrical properties were evaluated. Mg₃Sb₂ exhibited semiconductor behavior, Mg₃Bi₂ showed semimetal behavior, and in the superlattice, Mg₃Bi₂ layers dominated carrier conduction. These structural characteristics were discussed in detail using pole figures and reciprocal space mapping.
