The Influence of Surface Coatings on Exo-Electron Emission During Fatigue

A survey of exo-electron emission literature has shown that the mechanism of exo-emission phenomena has yet to be ascertained. Also, there is probably no unique mechanism that will apply to all the exo-emission observations reported. For exo-emission to occur, trapping centers must first be formed to store electrons. Once such centers are formed, they can be made to give up their trapped electrons by the stimulation of light or oxygen. Future investigations will employ light-transparent films for collecting exo-electrons. Also, a carefully controlled experiment is necessary to detect the emission of exo-electrons from the surface of fatiguing metals. Investigations will include high-vacuum fatigue tests, autoradiography, and solid state collector experiments, and will provide a basis for future research on semiconductor layer collection.
