Experimental and theoretical description of the quantum plasmon in dSNCs

Spectroscopic investigation: i) standard steady-state investigation; ii) ultrafast measurements; iii) near-field scanning microscopy and scattering-scanning near-field optical microscopy (S-SNOM) capable of probing single particle LSPR. Theoretical evaluation: i) Multi-scale theoretical models; ii) numerical tools and simulations; iii) density functional theory, tight-binding, empirical FT and local density approximation (LDA) procedures used to calculate the groundstate; iV) time-dependent LDA (TDLDA), based on the random phase approximation (RPA), to compute absorption spectra.
