Connecting electron and phonon spectroscopy data to consistently determine quasiparticle-phonon coupling on the surface of topological insulators
Colin Howard, M. El-Batanouny
Photoemission and phonon spectroscopies have yielded widely varying estimates of the electron-phonon coupling constant λ on the surfaces of topological insulators, even for a parti…
Magneto-transport in copper-doped noncentrosymmetric BiTeI
Chang-Ran Wang, Jen-Chuan Tung, S. Sankar +5
BiTeI exhibits large Rashba spin splitting due to its noncentrosymmetric crystal structure. The study of chemical doping effect is important in order to either tune the Fermi level…
Anomalous behavior in the phonon dispersion of the (001) surface of BiTe determined from helium atom-surface scattering measurements
Colin Howard, M. El-Batanouny, R. Sankar +1
We employ inelastic helium atom-surface scattering to measure the low energy phonon dispersion along high-symmetry directions on the surface of the topological insulator BiTe$_…
Enhanced quasiparticle dynamics of quantum well states: the giant Rashba system BiTeI and topological insulators
V. Gnezdilov, P. Lemmens, D. Wulferding +5
In the giant Rashba semiconductor BiTeI electronic surface scattering with Lorentzian linewidth is observed that shows a strong dependence on surface termination and surface potent…
