Study of the Interaction of Light with sub-Micron Metallic Surfaces: Final Progress Report

摘要

This program was largely concerned with the illumination of sub-micron metallic surfaces with intense laser light. This experimental arrangement, often referred to as photofield emission, is a technique that provides a convenient way of studying a variety of surface specific phenomena under intense laser illumination. Apart from the emphasis on small surfaces, the proposed experiments differ from conventional photoemission studies because a probe of the final state spectrum of emitted electrons populated by low photon energies can be readily achieved. Emphasis is therefore given to low photon energies and modest CW light intensities. An important feature of these experiments is the ability to investigate the effects of a strong applied electric field on the surface under illumination. (ERA citation 13:019943)
