Temperature dependence of the topological phase transition of BiTeI from first principles
A topological phase transition from a trivial insulator to a Z_{2} topological insulator requires the bulk band gap to vanish. In the case of noncentrosymmetric materials, these phases are separated by a gapless Weyl semimetal phase. However, at finite temperature, the gap is affected by atomic moti...
