Electron dynamics in topological insulator based semiconductor-metal interfaces (topological p-n interface based on Bi2Se3 class)
L. Andrew Wray, Suyang Xu, Madhab Neupane +10
Single-Dirac-cone topological insulators (TI) are the first experimentally discovered class of three dimensional topologically ordered electronic systems, and feature robust, massl…
A new experimental approach for the exploration of topological quantum phenomena : Topological Insulators and Superconductors
M. Zahid Hasan, David Hsieh, Yuqi Xia +3
The three-dimensional topological insulator (originally called "topological insulators") is the first example in nature of a topologically ordered electronic phase existing in thre…
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}…
Dirac cone in iron-based high Tc superconductors
M. Zahid Hasan, B. Andrei Bernevig
The band structure of iron-based superconductors gives rise to yet another scenario for the appearance of Dirac fermions. A viewpoint on "Observation of Dirac cone electronic dispe…
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…
