Concluding Remarks

Abstract

This monograph has the intention of revealing not only fundamental, but also applied aspects of the spectroscopy of ion-induced energetic electrons that are produced by the binary-encounter processes in solids bombarded by fast ions. The binary-encounter electron yield considered here results from multiple scattering of energetic ions and electrons, which would require numerical calculations in an orthodox approach. It has been demonstrated, however, that the electron yield under channeling as well as random incidence conditions can be explained by the model based on a useful concept, i.e. the effective surface layer for production of the electron yield, which was deduced from the experimental data covering wide ranges of the ion energy and ion species.
