graphene plasmonics

Graphene plasmonics studies how plasmons—collective oscillations of electrons—behave on a sheet of graphene, a one-atom-thick layer of carbon atoms. When light interacts with graphene, it can excite these plasmons, enabling the concentration of electromagnetic energy into extremely small areas. This property allows for highly sensitive sensors, efficient light manipulation at the nanoscale, and advances in photonic devices. Since graphene's plasmons are tunable via electrical signals, it offers a versatile platform for developing next-generation optical and electronic technologies.
