Coherent Topological Transport on the Surface of Bi2Se3
Dohun Kim, Paul Syers, Nicholas P. Butch +2
The two-dimensional (2D) surface state of the three-dimensional strong topological insulator (STI) is fundamentally distinct from other 2D electron systems in that the Fermi arc en…
Layer-by-layer entangled spin-orbital texture of the topological surface state in Bi2Se3
Z. -H. Zhu, C. N. Veenstra, G. Levy +7
We study Bi2Se3 by polarization-dependent angle-resolved photoemission spectroscopy (ARPES) and density-functional theory slab calculations. We find that the surface state Dirac fe…
Hybridization, Inter-Ion Correlation, and Surface States in the Kondo Insulator SmB6
Xiaohang Zhang, N. P. Butch, P. Syers +3
As an exemplary Kondo insulator, SmB6 has been studied for several decades; however, direct evidence for the development of the Kondo coherent state and the evolution of the electr…
Magnetothermoelectric properties of Bi2Se3
B. Fauqué, N. P. Butch, P. Syers +6
We present a study of entropy transport in Bi2Se3 at low temperatures and high magnetic fields. In the zero-temperature limit, the magnitude of the Seebeck coefficient quantitative…
Intrinsic Electron-Phonon Resistivity in Bi2Se3 in the Topological Regime
Dohun Kim, Qiuzi Li, Paul Syers +4
We measure the temperature-dependent carrier density and resistivity of the topological surface state of thin exfoliated Bi2Se3 in the absence of bulk conduction. When the gate-tun…
Topological insulator quantum dot with tunable barriers
Sungjae Cho, Dohun Kim, Paul Syers +3
Thin (6-7 quintuple layer) topological insulator Bi2Se3 quantum dot devices are demonstrated using ultrathin (2~4 quintuple layer) Bi2Se3 regions to realize semiconducting barriers…
