Topological insulator in a Bi-BiSe infinitely adaptive superlattice phase
T. Valla, Huiwen Ji, L. M. Schoop +10
We report spin- and angle-resolved photoemission studies of a topological insulator from the infinitely adaptive series between elemental Bi and BiSe. The compound, based o…
Topological Surface States and Dirac point tuning in ternary Bi2Te2Se class of topological insulators
M. Neupane, S. -Y. Xu, L. A. Wray +14
Using angle-resolved photoemission spectroscopy, we report electronic structure for representative members of ternary topological insulators. We show that several members of this f…
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…
Bi2Te1.6S1.4 - a Topological Insulator in the Tetradymite Family
Huiwen Ji, J. M. Allred, M. K. Fuccillo +5
We describe the crystal growth, crystal structure, and basic electrical properties of Bi2Te1.6S1.4, which incorporates both S and Te in its Tetradymite quintuple layers in the moti…
Bulk Intergrowth of a Topological Insulator with a Room Temperature Ferromagnet
Huiwen Ji, J. M. Allred, Ni Ni +6
We demonstrate that the layered room temperature ferromagnet Fe7Se8 and the topological insulator Bi2Se3 form crystallographically oriented bulk composite intergrowth crystals. The…
