Author(s): Y. H. Wang, D. Hsieh, E. J. Sie, H. Steinberg, D. R. Gardner, Y. S. Lee, P. Jarillo-Herrero, and N. Gedik We perform time- and angle-resolved photoemission spectroscopy of a prototypical topological insulator (TI) Bi 2 Se 3 to study the ultrafast dynamics of surface and bulk electrons after photoexcitation. By analyzing the evolution of surface states and bulk band spectra, we obtain their electronic tempe... [Phys. Rev. Lett. 109, 127401] Published Thu Sep 20, 2012
