Optical Nanoimaging of Graphene Plasmons (IMAGE) Elhuyar Fundazioa Caption This image shows optical nanoimaging of graphene plasmons. The upper panel shows a sketch of the imaging method. A laser illuminated scanning tip launches plasmons on graphene. Detection is by recording the light backscattered from the tip. The lower panel shows optical image of graphene, where the fringes visualize the interference of the graphene plasmons.
