Photoemission study of onionlike carbons produced by annealing nanodiamonds

“…51,60 The reasons for such a large separation between the two components are not clear, however, fitting with a smaller difference in binding energy did not give a good agreement with the experimental spectrum. A similar separation between sp 2 and sp 3 components was found in Ref.…”

“…49 However, this value of binding energy is 0.3 eV larger than values previously reported for the C1s binding energy in graphite. 50,51 The possible reasons for this difference will be discussed in the next section. We attribute the peak at 286.10± 0.05 eV binding energy with a pronounced shoulder at higher binding energy to sp 3 bound carbon and carbon bound to different oxygen-containing groups.…”

“…The fitting with one component for oxygen-containing groups gave a 1.5± 0.1 eV difference in the binding energy of the sp 2 and sp 3 components, which is significantly larger than the differences of 0.9 eV reported for amorphous carbon 49,59 and 0.8 eV for diamondlike-carbon films. 51,60 Therefore, we excluded this fit from our consideration.…”

“…Even for a hydrocarbon peak, the deconvolution enables us to distinguish sp 3 and sp 2 carbons, in which the peaks for sp 3 and sp 2 are located at around 285.2 and 284.3 eV, respectively (Mizokawa et al,1987;J. Diaz et al, 1996).…”

Stoichiometry of the diamond/silicon interface and its influence on the silicon content of diamond films

“…These are assigned to carbidic ͑SiC͒, pure carbon ͑dia-mond, nondiamond, graphite͒ and hydrogenated/hydrogen terminated carbon ͑diamond, nondiamond͒, respectively. [25][26][27] It is, however, not possible to distinguish between the different carbons such as diamond, nondiamond, and graphitic by XPS because of the very similar binding energies (ϳ284.5 eV). The presence of SiC was further confirmed by scanning in the Si(2 p) region.…”
