Interband transitions of electrons in a gapped graphene monolayer are highlystimulated near the Fermi surface when a high-frequency electric wave of weakintensity and a strong constant electric field are superposed in the plane ofthe flake. We consider this phenomenon equivalent to the Franz-Keldysh effect,paying particular attention to the regime where the photon energy linked to thefast-oscillating field is just below the graphene gap, so that the quantumtransitions still occur through tunneling effects while being facilitated bythe one-photon absorption channel. In the considered parameter regime thephoto-catalyzed current linked to the described setup is shown to exceed theone driven by the strong field solely by several orders of magnitude.Conditions to relieve the impact of the field's finite extension are discussed,and a formula for the residual current density is derived. The robustness ofour assessment supports the viability of detecting this phenomenon in graphene,thus providing a simulation of the dynamically-assisted Schwinger mechanism inQED.
