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…
Electron-Phonon Coupling on the Surface of Topological Insulators
Xuetao Zhu, Colin Howard, Jiandong Guo +1
Topological insulators (TIs) are materials that have a bulk electronic band gap like an ordinary insulator but have protected conducting states on their surface. One of the most in…
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$_…
Electron-phonon Coupling on the Surface of the Topological Insulator Bi2Se3: Determined from Surface Phonon Dispersion Measurements
Xuetao Zhu, Luiz Santos, Colin Howard +4
In this letter we report measurements of the coupling between Dirac fermion quasiparticles (DFQs) and phonons on the (001) surface of the strong topological insulator Bi2Se3. While…
Interaction of Phonons and Dirac Fermions on the Surface of Bi2Se3: A Strong Kohn Anomaly
Xuetao Zhu, L. Santos, R. Sankar +5
We report the first measurements of phonon dispersion curves on the (001) surface of the strong three-dimensional topological insulator Bi2Se3. The surface phonon measurements were…
