Current amplification and relaxation in Dirac systems
Alexandra Junck, Gil Refael, Felix von Oppen
We study how electron-electron (e-e) interactions affect the current carried by excited electrons and holes in Dirac systems such as graphene or topological insulators. We find tha…
Transport through a disordered topological-metal strip
Alexandra Junck, Kun W. Kim, Doron L. Bergman +2
Features of a topological phase, and edge states in particular, may be obscured by overlapping in energy with a trivial conduction band. The topological nature of such a conductor,…
Photocurrent Response of Topological Insulator Surface States
Alexandra Junck, Gil Refael, Felix von Oppen
We study the photocurrent response of topological insulator surface states to circularly polarized light for arbitrary oblique incidence. We describe the surface states within a Di…
