Topological insulators offer promising potential for nanoscale, high-frequency devices, yet controlling surface plasmon properties remains challenging. Here, the authors grow Bi2Se3/C60 heterostructures with exceptional crystallinity, using electron energy loss spectroscopy and density functional theory to reveal significant π state hybridization and quenching of 2D plasmons.
