A tight-binding model for the band dispersion in rhombohedral topological insulators over the whole Brilluoin zone

Carlos Mera Acosta, Matheus P. Lima, Antonio J. R. da Silva +2

We put forward a tight-binding model for rhombohedral topological insulators materials with the space group $D_{3d}^5(R\bar{3}m)$. The model describes the bulk band structure of…
