Gate tunable quantum Hall effects in defect-suppressed Bi2Se3 films
N. Koirala, M. Salehi, J. Moon +1
Despite many years of efforts, attempts to reach the quantum regime of topological surface states (TSS) on an electrically tunable topological insulator (TI) platform have so far f…
Coexistence of bulk and surface states probed by Shubnikov-de Haas oscillations in BiSe with high charge-carrier density
E. K. de Vries, S. Pezzini, M. J. Meijer +6
Topological insulators are ideally represented as having an insulating bulk with topologically protected, spin-textured surface states. However, it is increasingly becoming clear t…
Surface vibrational modes of the topological insulator BiSe observed by Raman spectroscopy
H. -H. Kung, M. Salehi, I. Boulares +10
We present polarization resolved Raman scattering study of surface vibration modes in the topological insulator BiSe single crystal and thick films. Besides the four Raman…
High-Resolution Faraday Rotation and Electron-Phonon Coupling in Surface States of the Bulk-Insulating Topological Insulator CuBiSe
Liang Wu, Wang-Kong Tse, M. Brahlek +5
We have utilized time-domain magneto-terahertz spectroscopy to investigate the low frequency optical response of topological insulator CuBiSe and BiSe film…
Time-resolved terahertz dynamics in thin films of the topological insulator BiSe
R. Valdés Aguilar, J. Qi, M. Brahlek +7
We use optical pump--THz probe spectroscopy at low temperatures to study the hot carrier response in thin BiSe films of several thicknesses, allowing us to separate the bul…
Evidence of unconventional low-frequency dynamics in the normal phase of Ba(Fe1-xRhx)2As2 iron-based supercondutors
L. Bossoni, P. Carretta, W. P. Halperin +4
This work presents 75As NMR spin echo decay rate (1/T2) measurements in Ba(Fe1-xRhx)2As2 superconductors, for 0.041 < x < 0.094. It is shown that 1/T2 increases upon cooling, in th…
