Аннотация:We experimentally realize nano-antennas based on hybrid silicon-gold nanoparticles (NPs). The silicon
particles covered by clusters of small metal NPs are fabricated from a liquid phase under the effect of
the laser irradiation. The complex nanoclusters containing both Si and Au components provide the
enhancement of the near-field intensity and the resonant light scattering associated with excitation of
multipole resonances in NPs. A strong sensitivity of the resonant light absorption to the hybrid particle
size and material parameters is experimentally documented and theoretically discussed. The results
demonstrate a high potentiality of the hybrid NPs for the realization of functional optical devices and
metasurfaces.
