Abstract

We report on a pneumatically coupled graphene pump system, comprising two cylindrical cavities of 3 femtoliter connected by a narrow trench, all covered by a thin few-layer graphene membrane. Local electrodes at the bottom of each cavity enable electrostatic pressure control and manipulation of gas flow through the channel. Using laser interferometry, we measure graphene displacement as a function of driving amplitude and frequency, thus providing proof-of-principle for using graphene membranes to pump attoliter quantities of gases and demonstrating pneumatic actuation at the nanoscale.
