Abstract
The effect of synchrotron beam irradiation on ${\mathrm{C}}_{60}$F${}_{48}$ 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 ${\mathrm{C}}_{60}$F${}_{48}$ and the formation of a fluorine-terminated surface with a (2\ifmmode\times\else\texttimes\fi{}1) surface reconstruction. This is accompanied by a loss in the ${\mathrm{C}}_{60}$F${}_{48}$-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.
