Strong nonlinear terahertz response induced by Dirac surface states in Bi2Se3 topological insulator

Strong nonlinear terahertz response induced by Dirac surface states in Bi2Se3 topological insulator

The terahertz response of topological insulator surface states, in which relativistic electrons are protected from backscattering, possesses potential optic and plasmonic applications. Here, the authors demonstrate a nonlinear absorption response of Bi2Se3to terahertz electric fields.
