Effect of Tamm surface states on hot electron generation and Landau damping in nanostructures metal-semiconductor
Alexander V. Uskov, Igor V. Smetanin, Igor E. Protsenko +2
The hot electron generation in plasmonic nanoparticles is the key to efficient plasmonic photocatalysis. In the paper, we study theoretically for the first time the effect of Tamm…
Electrostatic control over optically-pumped hot electrons in optical gap antennas
Adrian Agreda, Sviatlana Viarbitskaya, Igor V. Smetanin +3
We investigate the influence of a static electric field on the incoherent nonlinear response of an unloaded electrically-contacted nanoscale optical gap antenna. Upon excitation by…
Effect of quantized conductivity on the anomalous photon emission radiated from atomic-size point contacts
Mickaël Buret, Igor V. Smetanin, Alexander V. Uskov +2
We observe anomalous visible to near-infrared electromagnetic radiation emitted from electrically driven atomic-size point contacts. We show that the number of photons released str…
Biased Nanoscale Contact as Active Element for Electrically Driven Plasmonic Nanoantenna
Alexander V. Uskov, Jacob B. Khurgin, Mickael Buret +3
Electrically-driven optical antennas can serve as compact sources of electromagnetic radiation operating at optical frequencies. In the most widely explored configurations, the rad…
