Helicity dependent photocurrent in electrically gated (Bi,Sb)_2Te_3 thin films
Yu Pan, Qing-Ze Wang, Andrew L. Yeats +7
Circularly polarized photons are known to generate a directional helicity-dependent photocurrent in three-dimensional topological insulators at room temperature. Surprisingly, the…
Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator
Duming Zhang, Anthony Richardella, David W. Rench +12
The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…
Coherent Heteroepitaxy of Bi2Se3 on GaAs (111)B
A. Richardella, D. M. Zhang, J. S. Lee +6
We report the heteroepitaxy of single crystal thin films of Bi2Se3 on the (111)B surface of GaAs by molecular beam epitaxy. We find that Bi2Se3 grows highly c-axis oriented, with a…
