Abstract

We describe very fast electron dynamics for a graphene nanoribbon (GNR) driven by a control electric field in the terahertz frequency regime. The electron mobility of the GNR can be calculated through the nonlinear Boltzmann transport equation by numerical simulation. As the particular relation between the light transmittance and the conductivity of GNR, we’ll make it that the light transmittance is function of the external electric field. The results indicate the terahertz modulation depth of graphene nanoribbon is 2.6%.
