A sudden collapse in the transport lifetime across the topological phase transition in
Liang Wu, M. Brahlek, R. Valdés Aguilar +7
Topological insulators (TIs) are newly discovered states of matter with robust metallic surface states protected by the topological properties of the bulk wavefunctions. A quantum…
Giant plateau in the THz Faraday angle in gated Bi2Se3
Gregory S. Jenkins, Andrei B. Sushkov, Don C. Schmadel +5
We report gated terahertz Faraday angle measurements on epitaxial Bi2Se3 thin films capped with In2Se3. A plateau is observed in the real part of the Faraday angle at an onset gate…
Aging and reduced bulk conductance in thin films of the topological insulator BiSe
R. Valdés Aguilar, L. Wu, A. V. Stier +5
We report on the effect of exposure to atmospheric conditions on the THz conductivity of thin films of the topological insulator BiSe. We find: 1) two contributions of mobi…
THz response and colossal Kerr rotation from the surface states of the topological insulator BiSe
R. Valdés Aguilar, A. V. Stier, W. Liu +8
Ordered states of matter are typically categorized by their broken symmetries. With the ordering of spins in a ferromagnet or the freezing of a liquid into a solid, the loss of sym…
