Plasmon drag effect pinning and molecule adsorption (Conference Presentation)
Author(s): Maxim Durach

Paper Abstract

This talk will describe the recent progress in plasmon drag effect studies. Recently, we have predicted that illumination of metals by light induces a new force on electrons – which we called the spin force. This force should result in pinning of the net plasmon-induced electromotive force to an atomically thin layer at the metal interface [Durach, Noginova, Phys. Rev. B 96, 195411 (2017)]. Consequently, the plasmonic group at NIST conducted experiments that show that plasmon drag effect (light-induced current) is different in ambient air and in 10-3 Pa vacuum and depends on the molecules adsorbed at the metal interface [Strait et al, arXiv:1812.01673 (2018)], confirming our prediction about the plasmon drag pinning to the atomic layer at the metal interface. Thus our prediction of plasmon drag pinning paves way for a multitude of applications in physics, chemistry and surface science.
