Quantum kinetic equations approach to the description of chemical reactions between adparticles at a metallic surface

Abstract

Adparticle dynamics at a metallic surface is studied by means of quantum kinetic equations. Kinetic equations of the reaction-diffusion type are written down for nonequilibrium one-particle distribution functions of the adsorbate up to the second order in the tunnelling constants and amplitudes of chemical reactions.
