Directional control of the diffusion of excitons is desired for excitonic devices, but being neutrally charged they can’t be transported by applying a bias voltage as for conventional electronic transport. It is now shown that surface acoustic waves can direct the flux of excitons over micrometre distances, even at room temperature.
