Thermoelectric Mg3Bi2 thin films were grown on sapphire substrates with different orientations using MBE, and their structures were evaluated. RHEED and XRD revealed epitaxial growth on both substrates with negligible strain along the c-axis. Pole figure measurements showed differences in symmetry depending on the substrate, clarifying the epitaxial relationship.
