Photocurrents in Bi2Se3: bulk versus surface, and injection versus shift currents
Derek A. Bas, Rodrigo A. Muniz, Sercan Babakiray +3
Optical injection and detection of charge currents can complement conventional transport and photoemission measurements without the necessity of invasive contact that may disturb t…

Coherent control of injection currents in high-quality films of Bi2Se3
D. A. Bas, K. Vargas-Velez, S. Babakiray +5
Films of the topological insulator Bi2Se3 are grown by molecular beam epitaxy with in-situ reflection high-energy electron diffraction. The films are shown to be high-quality by X-…
