The initial stage of electrical breakdown in metal-dielectric-metal structures is considered. In such structures, channels of electronic conductivity and pores are formed near microscopic peaks on the surface of the metallic electrode under the influence of an external constant electric field in the dielectric. Formulas are obtained for calculating the natural oscillation frequency of the resonant pores and conditions for their irreversible growth. The proposed theory may be used for identification and elimination of fabrication defects.
