Abstract
A mathematical model of a SEM (scanning electron microscopy) signal formed by true secondary electrons, i.e., electrons emitted by a sample under the action of primary and inelastically scattered electrons, is proposed. Good agreement between the simulated signals and experimental results obtained on an Auriga (Carl Zeiss) device is attained.
