Control over topological insulator photocurrents with light polarization
J. W. McIver, D. Hsieh, H. Steinberg +2
Three-dimensional topological insulators represent a new quantum phase of matter with spin-polarized surface states that are protected from backscattering. The static electronic pr…

Selective probing of photo-induced charge and spin dynamics in the bulk and surface of a topological insulator
D. Hsieh, F. Mahmood, J. W. McIver +3
Topological insulators possess completely different spin-orbit coupled bulk and surface electronic spectra that are each predicted to exhibit exotic responses to light. Here we rep…

Nonlinear optical probe of tunable surface electrons on a topological insulator
D. Hsieh, J. W. McIver, D. H. Torchinsky +3
We use ultrafast laser pulses to experimentally demonstrate that the second-order optical response of bulk single crystals of the topological insulator BiSe is sensitive to…
