Surface plasmons are coherent delocalized electron oscillations that exist at the interface between a metal and a dielectric, which can be excited by light at specific frequencies. They are pivotal in enhancing electromagnetic fields at surfaces, leading to applications in sensing, photonic circuits, and improving the efficiency of photovoltaic devices.
