High pressure transport properties of the topological insulator Bi2Se3
J. J. Hamlin, J. R. Jeffries, N. P. Butch +6
We report x-ray diffraction, electrical resistivity, and magnetoresistance measurements on Bi2Se3 under high pressure and low temperature conditions. Pressure induces profound chan…
Evidence for Dirac Nodes from Quantum Oscillations in SrFeAs
Mike Sutherland, D. J. Hills, B. S. Tan +9
We present a detailed study of quantum oscillations in the antiferromagnetically ordered pnictide compound SrFeAs as the angle between the applied magnetic field and crysta…
Rashba spin-splitting control at the surface of the topological insulator Bi2Se3
Z. -H. Zhu, G. Levy, B. Ludbrook +11
The electronic structure of Bi2Se3 is studied by angle-resolved photoemission and density functional theory. We show that the instability of the surface electronic properties, obse…
Surface conduction of topological Dirac electrons in bulk insulating Bi2Se3
Dohun Kim, Sungjae Cho, Nicholas P. Butch +5
The newly-discovered three-dimensional strong topological insulators (STIs) exhibit topologically-protected Dirac surface states. While the STI surface state has been studied spect…
Spatially resolved femtosecond pump-probe study of topological insulator Bi2Se3
Nardeep Kumar, Brian A. Ruzicka, N. P. Butch +4
Carrier and phonon dynamics in Bi2Se3 crystals are studied by a spatially resolved ultrafast pump-probe technique. Pronounced oscillations in differential reflection are observed w…
