Modelling the localized surface plasmon resonance of nanoclusters of group III metals and semimetallic antimony

Surface plasmon resonance in metal nanodroplets formed by droplet epitaxy was studied numerically. Metals compatible with molecular beam epitaxy and semimetallic antimony are shown to be effective for plasmonic applications in infrared region. The resonance position can be controlled by varying the droplet size. The increase in the effective droplet size results in the linear redshift of the resonance wavelength. The nanodroplet parameters needed to match a particular quantum dot emission can be found.
