S04 - Phase-controlled photoemission from individual clusters at surfaces

Project description

Project S04 investigates plasmon-assisted photoelectron emission from faceted silver nanoparticles on substrates, aiming at a microscopic understanding of how near-field enhancement, particle geometry, symmetry breaking, and optical excitation shape the electron yield and emission direction. By applying time-of-flight PEEM, TEM and EELS to well-defined nanoparticles, the relationships between structure, plasmon modes, and electron emission are investigated. Phase- controlled excitation steers emission and selectively addresses plasmonic pathways.
