## Description

- description: Coulomb drag between adjacent electron and hole gases has attracted
    considerable attention, being studied in various two–dimensional systems, including
    semiconductor and graphene heterostructures. Here we report measurements of electron–hole
    drag in the Planckian plasma that develops in monolayer graphene in the vicinity
    of its Dirac point above liquid–nitrogen temperatures. The frequent electron–hole
    scattering forces minority carriers to move against the applied electric field
    due to the drag induced by majority carriers. This unidirectional transport of
    electrons and holes results in nominally negative mobility for the minority carriers.
    The electron–hole drag is found to be strongest near room temperature, despite
    being notably affected by phonon scattering. Our findings provide better understanding
    of the transport properties of charge–neutral graphene, reveal limits on its hydrodynamic
    description and also offer insight into quantum–critical systems in general.
