    • Peak positions and intensities are determined by fitting two Gaussians to the measured spectra. The spectral shoulder at 250 nm is related to transition radiation and Bremsstrahlung resulting from the sudden velocity change of the injected electrons in the sample.

    • note
    • The dominance of the (1, 0) peak is the consequence of the specific excitation mechanism in the STM. Field-emitted electrons from the tip follow the surface normal and efficiently induce dipoles with (1, 0) orientation. In-plane oscillations are primarily excited by secondary processes, e.g., hot electron decays, leading to an extremely small excitation cross-section. The importance of secondary processes for the STM-induced light emission is manifested by the exponential dependence of the emission yield on the energy of injected electrons. In contrast, the calculated polarizability of well-ordered particle networks is dominated by the (1, 1) Mie mode.
