  We performed an investigation concerning bipolaron dynamics in armchair
graphene nanoribbons (AGNRs) under the influence of different electric field
and electron-phonon coupling regimes. By studying the response to the electric
excitation, we were able to determine the effective mass and terminal velocity
of this quasiparticle in AGNRs. Remarkably, bipolarons in narrower AGNRs move
as fast as the ones in conjugated polymers. Our findings pave the way to
enhance the understanding of the behavior of charge carriers in graphene
nanoribbons.
