Dirac point spectral weight suppression and surface "gaps" in nonmagnetic and magnetic topological insulators
Su-Yang Xu, L. A. Wray, N. Alidoust +7
It is predicted that electrons on the surface of a topological insulator can acquire a mass (massive Dirac fermion) by opening up a gap at the Dirac point when time-reversal symmet…
Direct observation of spin-polarized surface states in the parent compound of topological insulator Bi-Sb using spin-resolved-ARPES in a 3D Mott-polarimetry spin mode
D. Hsieh, Y. Xia, L. Wray +9
We report high-resolution spin-resolved photoemission spectroscopy (Spin-ARPES) measurements on the parent compound Sb of the first discovered 3D topological insulator Bi{1-x}Sb{x}…
Realization of an isolated Dirac node and strongly modulated Spin Texture in the topological insulator Bi2Te3
Su-Yang Xu, L. A. Wray, Y. Xia +12
The development of spin-based applications of topological insulators requires the knowledge and understanding of spin texture configuration maps as they change via gating in the vi…
Effects of iron doping on the topological insulator surfaces
L. A. Wray, Y. Xia, S. -Y. Xu +5
Topological insulators embody a newly discovered state of matter characterized by conducting spin-momentum locked surface states that span the bulk band gap. So far, most of the st…
Observation of Topological Order in the TlBiSe2 class : Probing the "spin" and "phase" on topological insulator surfaces
Su-Yang Xu, L. A. Wray, Y. Xia +9
A topological insulator is characterized by spin-momentum locking on its boundary. The spin momentum locking on the surface of a three dimensional topological insulator leads to th…
Discovery of several large families of Topological Insulator classes with backscattering-suppressed spin-polarized single-Dirac-cone on the surface
Su-Yang Xu, L. A. Wray, Y. Xia +9
Three dimensional (3D) topological insulators are novel states of quantum matter that feature spin-momentum locked helical Dirac fermions on their surfaces and hold promise to open…
