WebThe emission of SEs occurs throughout the intersection of the surface with the interaction volume, but as the beam electron flux density is the highest where the beam first enters the sample, the highest concentration of SEs also comes from this region. This fraction of the SE signal is what allows most high resolution SEM imaging.
