Abstract

This chapter reviews the status of intrinsic and extrinsic emissions from metals, which have undergone mechanical treatment in one form or another. It discusses tribostimulated, chemically stimulated, and thermally stimulated emissions. The chapter discusses the interpretation of photostimulated electron emission (PEEE) experiments from the theoretical point of view based on calculations and a series of experimental results. PEEE is a part of electron spectroscopy. The fatigue-enhanced PEEE of oxidized aluminum is enhanced by the absorption of the incident photon by the surface plasmons. Removing the oxide layer further increases the exo-electron emission since the attenuation effect of the oxide layers is absent.
