A Novel Quasi-One-Dimensional Topological Insulator in Bismuth Iodide $\beta$-Bi${}_4$I${}_4$

Gabriel Autès, Anna Isaeva, Luca Moreschini +16

Recent progress in the field of topological states of matter(1,2) has largely been initiated by the discovery of bismuth and antimony chalcogenide bulk topological insulators (TIs)…
