Calculation of charge-transfer plasmonic properties in one- and two-dimensional periodic systems

Subject of study. One- and two-dimensional periodic structures of nanoparticles connected by conducting linkers (bridges) were investigated. Aim of study. The aim was to develop a model for determining the properties of charge-transfer plasmons in one- and two-dimensional periodic systems of metal nanoparticles. Method. A hybrid quantum–classical approach, which was modified for periodic systems, was employed. Main results. The modified model was applied to two systems of periodic metal nanoparticles connected by conducting linkers. The corresponding results demonstrated that the plasmon frequencies were within the infrared range. Practical significance. The proposed hybrid model enables the calculation of the plasmon properties of complex periodic systems composed of connected metal nanoparticles, facilitating their application in various detectors.
