Intrinsic properties of bipolarons in armchair graphene nanoribbons

We performed an investigation concerning bipolaron dynamics in armchair graphene nanoribbons (AGNRs) under the influence of different electric fields and electron?phonon coupling regimes. By studying the response to the electric field, we determined 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.

Our investigation on bipolaron dynamics in armchair graphene nanoribbons (AGNRs) reveals that in different electric fields and electron-phonon coupling regimes, bipolarons in narrower AGNRs move as fast as those in conjugated polymers, shedding light on the behavior of charge carriers in graphene nanoribbons.
