## Description

- description: Surface acoustic waves (SAWs) can produce dynamic, periodic potentials
    inside 1D and 2D materials. Such periodic potentials have been used, or proposed,
    for a variety of applications, including acoustoelectric charge pumping. Here,
    we study acoustoelectric charge pumping in ultraclean graphene. Using a graphite
    top gate on boron-nitride-encapsulated graphene, we tune carrier concentration
    over a wide range, allowing us to study the acoustoelectric signal in the mixed-carrier
    and single-carrier regimes. In contrast to previous studies, our model describes
    the acoustoelectric signal at all carrier densities, including the charge neutrality
    point, demonstrating a complete quantitative understanding of acoustoelectric
    charge pumping in graphene. This quantitative model will aid future SAW-enabled
    probes of quantum phenomena in 2D materials and informs the design of novel SAW
    sensors.
