Surface electronic structure of the topological Kondo insulator candidate correlated electron system SmB6
Madhab Neupane, Nasser Alidoust, SuYang Xu +15
The Kondo insulator SmB6 has long been known to exhibit low temperature transport anomalies whose origin is of great interest. Here we uniquely access the surface electronic struct…
Oscillatory surface dichroism of an insulating topological insulator Bi2Te2Se
M. Neupane, S. Basak, N. Alidoust +16
Using circular dichroism-angle resolved photoemission spectroscopy (CD-ARPES), we report a study of the effect of angular momentum transfer between polarized photons and topologica…
Tunneling Tuned Spin Modulations in Ultrathin Topological Insulator Films
M. Neupane, A. Richardella, J. Sanchez-Barriga +18
Quantitative understanding of the relationship between quantum tunneling and Fermi surface spin polarization is key to device design using topological insulator surface states. By…
Surface electronic structure of a topological Kondo insulator candidate SmB6: insights from high-resolution ARPES
M. Neupane, N. Alidoust, S. -Y. Xu +13
The Kondo insulator SmB6 has long been known to exhibit low temperature (T < 10K) transport anomaly and has recently attracted attention as a new topological insulator candidate. B…
Electron behavior in topological insulator based P-N overlayer interfaces
L. A. Wray, M. Neupane, S. -Y. Xu +8
Topological insulators (TIs) are novel materials that manifest spin-polarized Dirac states on their surfaces or at interfaces made with conventional matter. We have measured the el…
Effects of iron doping on the topological insulator surfaces
L. A. Wray, Y. Xia, S. -Y. Xu +5
Topological insulators embody a newly discovered state of matter characterized by conducting spin-momentum locked surface states that span the bulk band gap. So far, most of the st…
