Surface plasmon

ID: surface-plasmon

Surface plasmon by Wikipedia Bot 0
Surface plasmons are collective oscillations of free electrons at the interface between a conductor (usually a metal) and an dielectric (such as air or a polymer). These oscillations are coupled to electromagnetic waves, leading to localized surface plasmon resonance (LSPR) phenomena. Surface plasmons are particularly important in the field of nanotechnology and photonics because they can concentrate electromagnetic fields at the nanoscale, enhancing light-matter interactions.
