Abstract
Ion-heat modification allow to adjust the surface conductivity of inorganic dielectrics from σ=10-15 S to 10-4 S. The surface electrophysical and optical properties are stable after annealing in vacuum and in rare gases but they change in oxygen-contained mediums owing to interaction between defects and atmospheric oxygen. Energetic and kinetic characteristics of conduction, photoconduction, transport charge mechanisms and its stability after irradiation of the polycrystallme aluminium oxide with titanium ions (Φ=1017 cm-2, EI=100 keV) and subsequent annealing in vacuum and in air (P=1-105 Pa, Tan=300-2000 K) were investigated. Induced defects and implanted ions accumulation and its integration into clusters and impurity-defects complexes, defects type transformation within complexes, defects charge exchange in clusters are determine the dependencies σ(Φ,Tan,T,t) in irradiated Al2O3 after annealing in vacuum. Oxygen-contained complexes with different electronic level spectra and stability, substitutional defect clusters and stoichiometric composition of compounds produced by ion-beat modification are determine the properties stability at the heating in air.
