Publisher Summary This chapter focuses on electron emission microscopy, which is characterized by the fact that the imaging electrons are emitted by the specimen itself, and the concepts “cathode” and “specimen” have identical meaning. The first electron emission images were taken by Goldstein in 1878 with a very simple experimental arrangement ...

Publisher Summary This chapter provides a review of the present state of knowledge of secondary electron emission (SE) by electrons from metals, insulators, and complex surfaces. A great deal of early work in SE was devoted to a careful analysis of the “fine structure” of the yield curve in which numerous small humps and inflexion points between zero
