Fluorination Of The Diamond Surface By Photoinduced Dissociation Of C60f48

The effect of synchrotron beam irradiation on C60F48 adlayers absorbed on the hydrogen-terminated C(100) diamond surface has been examined using core level photoelectron spectroscopy. Irradiation causes the dissociation of fluorine from the C60F48 and the formation of a fluorine-terminated surface with a (2x1) surface reconstruction. This is accompanied by a loss in the C60F48-induced surface transfer doping of the diamond substrate. The simplicity of this process makes it highly applicable to monofluoride surface patterning for nanoelectronic and surface functionalization applications of diamond.
