Ultrafast Electron Dynamics in the Topological Insulator Bi2Se3 Studied by Time-Resolved Photoemission Spectroscopy

Jonathan A. Sobota, Shuolong Yang, Dominik Leuenberger +6

We characterize the topological insulator Bi${}_2$Se${}_3$ using time- and angle- resolved photoemission spectroscopy. By employing two-photon photoemission, a complete picture of the…
