Researchers have found that the topological material trisodium bismuthide (Na3Bi) can be manufactured to be as “electronically smooth” as the highest-quality graphene-based alternative, while maintaining graphene’s high electron mobility. Na3Bi is a Topological Dirac Semimetal (TDS), considered a 3D equivalent of graphene in that it shows the same extraordinarily high electron mobility. In graphene, as…
