Atomistic description of nanoplasmonics: from near field to surface-enhanced Raman scattering

An atomistic electrodynamics model, where the NPs in terms of a macroscopic homogenous dielectric constant is replaced by an atomic representation with dielectric properties depending on the local chemical environment, successfully describes the plasmonics behavior in quantum size region. By using this model, we explored the near field fluctuation and the origin of the SERS varying with time evolution.

Imaging and spectroscopy on ultrasmall length scales and ultrafast time scales

Scattering-type scanning near-field optical microscopy (s-SNOM) has become a powerful tool to directly visualize the optical properties of solids on ultrasmall length scales, far beyond the diffraction limit of light. Using this technology fascinating phenomena like propagating phonon [1] or plasmon-polaritons [2,3], the formation of metallic puddles in vanadium dioxide [4], and even mid-infrared absorption bands of single molecules [5] could be visualize with <10nm spatial resolution.
