Abstract

Recently, the existence of an allotrope phase of bismuthene called pentaoctite, in which all hexagonal rings are replaced by either pentagons or octagons, has been proposed.[1,2] These structures show a sizeable bandgap, can be stable under strain, and have topological insulator behavior with protected surface nontrivial Dirac states. From this information, we extend our...
