Ultrafast Optical Excitation of a Persistent Surface-State Population in the Topological Insulator Bi2Se3

Jonathan A. Sobota, Shuolong Yang, James G. Analytis +4

Using femtosecond time- and angle- resolved photoemission spectroscopy, we investigated the nonequilibrium dynamics of the topological insulator Bi2Se3. We studied p-type Bi2Se3, i…
