The properties of electrically active centers formed in Si-SiO2 struct
ures as a result of argon ion implantation in the oxide layer ate inve
stigated, along with the processes of defect formation in the ion-impl
anted structures due to subsequent, less-energetic, external (e.g., fi
eld) influences. The investigations are carried out by electrophysical
and electroluminescence methods in an electrolyte-insulator-semicondu
ctor system at room temperature. It is established that argon ion impl
antation in the bulk of the oxide layer leads to the formation of elec
trically active centers outside the zone of localization of the implan
ted argon ions, and a model of their formation is proposed. (C) 1997Am
