Bulk and surface electronic structure of Bi${}_4$Te${}_3$ from $GW$ calculations and photoemission experiments

Dmitrii Nabok, Murat Tas, Shotaro Kusaka +6

We present a combined theoretical and experimental study of the electronic structure of stoichiometric Bi${}_4$Te${}_3$, a natural superlattice of alternating Bi${}_2$Te${}_3$ quintuple la…
