Plasmon transport in graphene

We have heard of charge transport of graphene and its control by external electrical biasing. In a recent work published in Nature Communications, a charge pulse travelling in plasmon mode in graphene to the GHz range can be modulated by applying an external magnetic field. The study paves way for further plasmonic applications of graphene in a controlled manner.
