## Description

- description: Graphene-based photonic structures have emerged as fertile ground for
    the controlled manipulation of surface plasmon polaritons (SPPs), providing a
    two-dimensional platform with low optoelectronic losses. In principle, nanostructuring
    graphene can enable further confinement of nanolightenhancing light-matter interactions
    in the form of SPP cavity modes. In this study, we engineer nanoscale plasmonic
    cavities composed of self-assembled C60 arrays on graphene. Using scattering-type
    scanning near-field optical microscopy (s-SNOM) in conjunction with first-principles
    density functional theory (DFT) calculations, we show that C60 assemblies behave
    as molecular plasmonic cavities, giving rise to precisely defined hole-doped regions
    within continuous samples of graphene. By tuning the deposition conditions of
    C60, the lateral dimensions of molecular cavities can be tailored to the SPP wavelength.
    Finite-element simulations verify the existence of SPP cavity modes, revealing
    a real-space pattern characteristic of confined SPPs. Thus, our study provides
    a straightforward scheme for tailoring SPP mode volume by leveraging molecular
    self-assembly.
