Abstract
Over a decade ago, a theory based on Paschen´s law was proposed to unify electrical breakdown in gaseous, liquid, and solid dielectrics. In liquids, the mechanism proposed was the growth of vapor bubbles by the electrical heating accompanying electron avalanche. However, if submicroscopic bubbles pre-exist in liquid dielectrics before the electric field is applied, the formation of vapor bubbles would not be required to explain breakdown. In solid dielectrics, the submicroscopic bubbles would be formed in the liquid phase during solidification. These submicroscopic bubbles, called Plancktons, are a consequence of the Planck theory of sonoluminescence (SL) formulated to explain the VIS photons observed in the cavitation of H2O. The Plancktons grow from random density fluctuations by the brief, but intense pressures that accompany cavity QED to diameters that exceed the mean free path of electrons in the dielectrics. Within the Planckton, the electrons are free to accelerate under the applied electric field and exceed the 5 eV necessary for the ionization of the dielectric molecules in the Planckton wall. Subsequently, the dielectric undergoes breakdown as electron avalanche cascades through other Plancktons in the dielectric
