We have performed calculations using the local density approximation (LDA) of density functional theory and the one-shot GW approximation within the all-electron full-potential linearized augmented-plane-wave (FLAPW) formalism, fully taking into account spin-orbit coupling. Quasiparticle effects produce significant changes in the band structure of Bi2Te3 when compared to LDA. Experimental and calculated results are compared in the spectral regions where distinct differences between the LDA and GW results are present. Overall a superior agreement with GW is found, highlighting the importance of many-body effects in the band structure of this family of topological insulators.}, cin = {IAS-1 / PGI-1}, ddc = {530}, cid = {I:(DE-Juel1)IAS-1-20090406 / I:(DE-Juel1)PGI-1-20110106}, pnm = {422 - Spin-based and quantum information (POF2-422)}, pid = {G:(DE-HGF)POF2-422}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000341256500001}, doi = {10.1103/PhysRevB.90.075105}, url = {https://juser.fz-juelich.de/record/154918}, }
