GW study of pressure-induced topological insulator transition in group-IV tellurides

We calculate the electronic structure of the narrow gap semiconductors PbTe, SnTe, and GeTe in the cubic phase using density functional theory (DFT) and the G_{0}W_{0} method. Within DFT, we show that the band ordering obtained with a conventional semilocal exchange-correlation approximation is corr...
