Effet Poole-Frenkel dans le monoxyde de silicium dope

The influence of electrical field on the electrical properties of pure or doped silicon monoxyde films has been examined. After analysis and confrontation of the experimental results obtained by direct and alternative currents and by thermally stimulated currents, it has been shown that the same Poole-Frenkel effect appears in these different circumstances. The explanation is based on the heterogeneities in amorphous solids.
