TWO-DIMENSIONAL FILM OF GRAPHITE ON SURFACE OF TRANSIENT METALS

By Eugeny Victorovich Rutkov

Abstract

The aim is to investigate the adsorbing carbon-transient metal systems in single experimental conditions in the multi-purpose electronic spectrometer by means of the combination of the up-to-date surface diagnostics methods (electronic Auger-spectroscopy, thermodesorbing spectroscopy, contact difference of potentials a.o.). The total physical picture of interacting carbon with transient metals has been developed, the role of the two-dimensional graphite layer and other states of the surface carbon on the metals in the adsorption, desorption and catalysis phenomena, in the processes of forming initial stages on the growth of different films has been revealed. A number of the fundamental kinetical and energetical parameters connected with transport of the surface carbon - desorption, migration, diffusion of carbon between surface and volume of the metal, growth and solution of the graphite islands a.o. has been obtained. The developed source of the carbon atoms has been introduced in the Physical-Technical Institute (Russian Academy of Sciences), St.-Petersburg State University and in Institute of Catalysis (Russian Academy of Sciences) and can find application in the field of studying physics and chemistry of the atomic carbon on the surface.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
