Аннотация

The effect of the insulator-conductor transition of surface layers of oxides by ion bombardment was investigated by the example of doped LiNbO 3 single crystals. The important role of reduction in modification of conducting properties of the ion-irradiated crystals was established. The action of reduction on the electric characteristics of crystals LiNbO 3 is similar to that of ion bombardment. A new band of optical absorption with a maximum at 3.7 eV caused by presence of Mg impurity in LiNbO3 + MgO was founded. The comparative analysis of electric properties of reduced and irradiated by Ar+ ions crystals shows, that conductivity of the lithium niobate ion-modified layers is carried out by polarons hopping.
