The Development of the Atomic Theory of the Formation of a New Phase in Adsorbirivannyh Layers in an External Electric Field

Abstract

The article deals with the nucleation rate in the development of the atomic theory. The expression for the calculation of heterogeneous nucleation rate in adsorbed layers in an external electric field, which allows for the stability criterion nucleus of a new phase. For example, the values of nickel electrocrystallisation nucleation rate in the development of the atomic theory and the classical theory of nucleation. A comparison with the experimental values. It is shown that at high overvoltage at the cathode developed atomic theory gives values of the nucleation rate closer to the experimental. Keywords: atomic theory of nucleation of a new phase, the nucleation rate, the adsorbed layer, the binding energy, the activation energy of surface diffusion.
