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…
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}…
Helical magnetism and structural anomalies in triangular lattice α-SrCr2O4
S E Dutton, E Climent-Pascual, P W Stephens +4
α-SrCr2O4 has a triangular planar lattice of d3 Cr3+ made from edge sharing CrO6 octahedra; the plane shows a very small orthorhombic distortion from hexagonal symmetry. With a Wei…
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…
