Electron-Phonon Coupling and Surface Debye Temperature of Bi${}_2$Te${}_3$(111) from Helium Atom Scattering

Anton Tamtögl, Patrick Kraus, Nadav Avidor +9

We have studied the topological insulator Bi${}_2$Te${}_3$(111) by means of helium atom scattering. The average electron-phonon coupling $\lambda$ of Bi${}_2$Te${}_3$(111) is determined by adapt…
