Abstract

We use THz pulses to manipulate the optical response of MoSe₂ and WSe₂ monolayers, and MoSe₂/WSe₂ heterostructures. This method can be used to control excitonic populations on ultrafast time-scales, to access optical-driven nonlinear properties of matter and to design photonic devices with THz switches.
