Author(s): Takeshi Kondo, Y. Nakashima, Y. Ota, Y. Ishida, W. Malaeb, K. Okazaki, S. Shin, M. Kriener, Satoshi Sasaki, Kouji Segawa, and Yoichi Ando Quasiparticle dynamics on the topological surface state of Bi 2 Se 3 , Bi 2 Te 3 , and superconducting Cu x Bi 2 Se 3 are studied by 7 eV laser-based angle resolved photoemission spectroscopy. We find strong mode couplings in the Dirac-cone surface states at energies of ∼3 and ∼15–20 meV associated with an exce... [Phys. Rev. Lett. 110, 217601] Published Thu May 23, 2013
