In this work, we have evaluated the quasiparticle energies of ternary tetradymite Bi2Te2Se and Bi2Te2S using first-principles calculation within the G 0 W 0 methods. We have also performed a broad convergence tests in order to investigate the quasiparticle corrections to the structural parameters an...
