Ultrafast control and tailoring of surface plasmon generated electron pulses
Mr. Shawn Greig, PhD Student – University of Alberta, Canada
Numerous fundamental physical processes, such as DNA, lattice, and atomic-molecular dynamics occur on a femtosecond time scale. To probe such processes, one requires high spatial and temporal resolutions which can be achieved through ultrafast electron microscopy techniques. Recently, due to high plasmon (collective oscillations of conduction band electrons) field confinement, nanoplasmonics has been employed for the generation of high energy electron pulses on the nanoscale. Yet, many of the current SP based methods suffer from an inherent lack of control, both in electron beam characteristics (kinetic energy, pulse duration, current, etc.) and spatial directionality...
