Abstract:

A theoretical model of dielectric breakdown in solids has been proposed by Budenstein. In this model the breakdown process starts with the development of a critical local charge density. This density, in turn, causes chemical bonds to be broken and leads to the formation of a high density gaseous plasma, the conducting path for destructive breakdown. The present work explores the magnitude of the critical charge density by comparison of the bonding energies of the H2, H2, H2- and H2-- molecules. An ab initio calculation of the ground state of the H2-- molecule is performed and is the major contribution of this work. The implications of this calculation on the breakdown problem and on other problems are discussed.
