| Gaia: | Title from the title-page. The effect of the insulator-conductor transition of surface layers of oxides by ion bombardment was investigated by the example of doped LiNbO3 single crystals. The aim of this work is investigation the influence of impurity MgO, and also impurity of Fe2O3 on efficiency of conducting layers formation in LN crystals by ion bombardment. 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 LiNbO3 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. Threshold effect of MgO doping in LiNbO3 sample is observed around 10 mole% of MgO in LiNbO3 host and the origin of threshold effect is the formation of (MgNb) defects. 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.
