Surface Chemistry of Diamond Single Crystals.

Abstract

Diamond(100) was studied as a substrate for the adsorption of atomic hydrogen and fluorine. Both surface C-H bonds and surface C-F bonds are of importance in the tribological use of diamond film coating. A new and facile method for depositing surface fluorine on diamond has been developed. The method involves the photochemical dissociation of perfluoroalkyl iodide molecules depositing C(n)F(2n+1) groups on the diamond. These groups, upon thermal dissociation, produce surface C-F groups on the diamond. A patent application is being researched on this new method. jg
