Nonlinear Optical Probe of Tunable Surface Electrons on a Topological Insulator

Nonlinear Optical Probe of Tunable Surface Electrons on a Topological Insulator

We use ultrafast laser pulses to experimentally demonstrate that the second-order optical response of bulk single crystals of the topological insulator Bi2Se3 is sensitive to its surface electrons. By performing surface doping dependence measurements as a function of photon polarization and sample o...
