While electromagnetic resonance is used broadly in integrated
circuits works, the plasmonic resonance, the collective motions of
electrons, has not been used as much in electronics, as they typically
occur at optical frequencies with bulk conductors, with a notable
example being surface plasmons. When electrons are confined into low
dimensions (e.g., 1D with carbon nanotubes), they can occur at much
lower frequencies in the electronics regime. In this work, I will
present our experimental study of collective behaviors of interacting
electrons in low dimensions via their coupling with electromagnetic
fields and quantum effects. Due to the low dimensional plasmons’ unique
dynamical and quantum-mechanical properties, they can bring significant
advantages to electronics, aid in the study of the quantum systems
through enhanced interactions with matters with fine quantum splittings,
and can provide a frequency-domain means of studying electron-electron
interactions in one dimension, which are of significance in condensed
matter physics and many-body physics (e.g., Luttinger-Tomonaga liquid
theory). Our recent results highlight some of these significant benefits
of the low-dimensional plasmons.
