· JVASP-18469· Na3Bi

Na3Bi is an intermetallic ceramic compound composed of sodium and bismuth, representing an emerging class of topological materials studied for advanced electronic and photonic applications. This material is primarily of research interest rather than established commercial production, investigated for potential use in next-generation semiconductors, quantum devices, and energy conversion systems where its unique electronic band structure offers advantages over conventional materials. Its significance lies in its potential as a topological Dirac semimetal, making it valuable for fundamental materials science research and exploratory device engineering in fields demanding novel electronic transport properties.
