Localized surface
plasmon resonance (LSPR) in plasmonic nanoparticles
propels the field of plasmo-electronics, holding promise for transformative
optoelectronic devices through efficient light-to-current conversion.
Plasmonic excitations strongly influence the charge distribution within
nanoparticles, giving rise to electromagnetic fields that can significantly
impact the macroscopic charge flows within the nanoparticle housing
material. In this study, we present evidence of ultralow, unconventional
breathing currents resulting from dynamic irradiance interactions
between widely separated nanoparticles, extending far beyond conventional
electron (quantum) tunneling distances. We develop an electric analogue
model and derive an empirical expression to elucidate the generation
of these unconventional breathing currents in cascaded nanoplasmonic
systems under irradiance modulation. This technique and theoretical
model have significant potential for applications requiring a deeper
understanding of current dynamics, particularly on large nanostructured
surfaces relevant to photocatalysis, energy harvesting, sensing, imaging,
and the development of future photonic devices.
