Identification of the Chemical State of Carbon Atoms on Nanodiamond Powder SurfacesThe chemical state of carbon atoms on surface of nanodiamond particles is not known. In order to identify the chemical state the N(E) CKVV Auger spectroscopy with X-ray excitation of Auger emission have been used. According to the CKVV data on the surfaces of nanodiamond particles the carbon atoms have the same electron configuration as in graphite: σs1 σp2 π1, but opposite to graphite the π*π transitions do not take place. The phenomenon is evidence of absence of overlapping π-levels. The same chemical state takes place on surface of natural diamond (110) after H-treatment. The chemical state is inactive to environment.
