Abstract

The electron emission yields of insulators irradiated with ultra‐short pulsed X‐ray and electron beams differ significantly from those of metals. The main experimental results are reviewed and it is shown that the use of simple models for the transport and for the escape of the generated secondary electrons accounts for the role of the temperature and of the crystalline state on these yields (besides the role of the chemical composition of the insulator of interest).

When permanent irradiation is used, charging and damaging effects occur and correlated mechanisms are then considered. The present analysis concerns a wide variety of insulators (from oxides and halides to polymers) investigated with a wide variety of techniques (XPS, AES, SEM, etc.) and various practical consequences are also deduced.
