Abstract
A combination of N(E) Auger spectroscopy, X-ray excitation (XAES), electron energy loss spectroscopy (EELS), and valence band (VB) XPS have been used to study nanodiamond (ND) particles. These methods have different information depths of 1–2, 5–7, and 10–12 monolayers (ML), respectively, and an inherent spectral structure in the identification of sp2–sp3 -bonds. Our data show that the upper 1–2 ML of a ND particle consists of carbon atoms with sp2-bonds, which differ from those in well- known carbon compounds. The ND core is made up of diamond. Chemical reactions of the carbon atoms with the particle have been studied in-situ and ex-situ. The crutial role of the upper monolayer in the diamond growth has been established for both cases.
