Abstract
Carbon atoms chemisorbed on a Ni(111) surface were studied by Auger an d electron energy loss spectroscopies. The inspection of the carbon KV V Auger line for different values of ethylene pressure and exposure cl early indicates the formation of intermediate phases between pure carb idic and graphitic ones in the 10(-6)-10(-5) Torr range. Both Auger an d loss measurements confirm that finally a graphitic-like overlayer gr ows on the Ni(111) substrate for the highest exposure.
