Strong photoelectron emission from silver nanostructures
Abstract
Localized optically-nonlinear photoelectron emission from metal (silver) nanostructures under two-pulse emission has been developed for relatively low energy. For two-photon emission from random metal nanostructures, it has been shown that the coherent control allows one to move nanosize hot spots whose positions are controllable on a nanometer scale. It is proposed to use silver random planer composite and introduce this photoemission process as an ultrafast process, on femtosecond or subfemtosecond scale.
