  • Abstract
    We report that the surface states of Bi2Se3 exhibit strong nonlinear optical responses in the terahertz regime. The third order nonlinear optical conductance can be observed by applying a moderate electric field. The thermal influence on nonlinear optical responses of the surface states of Bi2Se3 is also studied over different temperature and frequency ranges.
