Quasiparticle band structure study of ternary mixed chalcogenide Bi2Te2S as topological insulator
In this paper, ternary mixed chalcogenide Bi2Te2S has been investigated using first principle within the density functional theory (DFT) calculation as well as many body perturbation theory within the GW quasiparticle approximations. For the DFT calculation, we have used generalize gradient approxim...
