▎ 摘　　要

We present a simulation framework based on the combination of Monte Carlo transport and Landauer-Buttiker formalism to model and optimize ballistic rectifiers exploiting the long mean-free-path of graphene. The influ-ence on the responsivity (i.e. the induced voltage normalized by the impinging power) of the main geometrical parameters, of bias and of different scattering mechanisms is critically analyzed.
