Observation of topologically protected Dirac spin-textures and πBerry's phase in pure Antimony (Sb) and topological insulator BiSb
D. Hsieh, Y. Xia, L. Wray +10
A topologically ordered material is characterized by a rare quantum organization of electrons that evades the conventional spontaneously broken symmetry based classification of con…
Time-reversal-protected single-Dirac-cone topological-insulator states in Bi2Te3 and Sb2Te3: Topologically Spin-polarized Dirac fermions with pi Berry's Phase
D. Hsieh, Y. Xia, D. Qian +12
We show that the strongly spin-orbit coupled materials Bi2Te3 and Sb2Te3 (first non-Bi topological insulator) and their derivatives belong to the Z2 (Time-Reversal-Protected, elast…
First observation of spin-helical Dirac fermions and topological phases in undoped and doped Bi2Te3 demonstrated by spin-ARPES spectroscopy
D. Hsieh, Y. Xia, D. Qian +12
Electron systems that possess light-like dispersion relations or the conical Dirac spectrum, such as graphene and bismuth, have recently been shown to harbor unusual collective sta…
Unconventional Fermi surface spin textures in the Bi_xPb_{1-x}/Ag(111) surface alloy
Fabian Meier, Vladimir Petrov, Sebastian Guerrero +4
The Fermi and Rashba energies of surface states in the Bi_xPb_{1-x}/Ag(111) alloy can be tuned simultaneously by changing the composition parameter x. We report on unconventional F…
First direct observation of Spin-textures in Topological Insulators : Spin-resolved ARPES as a probe of topological quantum spin Hall effect and Berry's phase
D. Hsieh, Y. Xia, L. Wray +10
A topologically ordered material is characterized by a rare quantum organization of electrons that evades the conventional spontaneously broken symmetry based classification of con…
Rashba type spin-orbit splitting of quantum well states in ultrathin Pb films
Hugo Dil, Fabian Meier, Jorge Lobo-Checa +3
A Rashba type spin-orbit splitting is found for quantum well states formed in ultrathin Pb films on Si(111). The resulting momentum splitting is comparable to what is found for sem…
