Abstract

Acoustic graphene plasmons (AGPs) hold promise for nanophotonics and sensing applications. Here, the authors observe enhanced in-plane scattering of mid-infrared AGPs caused by atomic steps on the substrate surface, suggesting potential strategies for controlling their propagation via substrate engineering.
