Abstract

Abstract: The electron–phonon coupling in the Rashba‐split two‐dimensional electron gas near the surface of the topological insulator Bi2 Se3 is studied by temperature‐dependent angleresolved photoemission. The coupling strength is found to be rather weak, with an electron–phonon mass enhancement parameter$ \lambda = 0.12(8). $ (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) Abstract : Angle‐resolved photoemission spectra reveal the two‐dimensional electron gas states on the surface of the topological insulator Bi2 Se3 . These states could be relevant for spintronics applications. The Letter by Barreto et al. studies the scattering of the electrons in the states by lattice vibrations.
