Resonant inverse photoemission via plasmons
Abstract
A large enhancement, up to a factor of 30, of the photon intensity is observed in inverse photoemission when the emitted photon energy equals the plasmon energy. The effect is explained as a resonance between a discrete channel, i.e., radiative decay of a plasmon, and the inverse photoemission continuum. Examples are shown for various structures of antimony films. © 1988 The American Physical Society.
