AbstractThe electron–phonon coupling in the Rashba‐split two‐dimensional electron gas near the surface of the topological insulator Bi 2 Se 3 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)
