Abstract

Study of the ion-induced-, photo- and exo-electron emission from a Sc doped MgO protective layer has been performed. It is established that doping with Sc increases photo- and especially exo-electron emission from MgO films while the ion-induced electron emission coefficient $\gamma$ stays unchanged.
