Measurement of Intrinsic Dirac Fermion Cooling on the Surface of the Topological Insulator Bi2Se3 Using Time-Resolved and Angle-Resolved Photoemission Spectroscopy
We perform time- and angle-resolved photoemission spectroscopy of a prototypical topological insulator (TI) Bi[subscript 2]Se[subscript 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 obtai...
