摘要

Angle-resolved x-ray photoelectron spectroscopy was used to investigate the surface of a diamondlike carbon film prepared by the ionized deposition method. We then analyzed the C 1s spectra using the Doniach-Sunjic (DS) [J. Phys. C 3, 285 (1970)] function convoluted with a Gaussian function. Consequently, we obtained four fitting curves for the carbon components in each spectrum, regardless of the assumption of the singularity index (α) in the DS function, which expresses the asymmetry of the C 1s spectrum. The curves were assigned in the order of binding energy to bulk sp~3 carbon (283.7-283.8 eV), bulk sp~2 carbon (284.2-284.3 eV), surface sp~2 carbon (284.7-284.8 eV), and surface sp~3 (285.3-285.4 eV) carbon. We further considered the influence of the assumption of α. Consequently, we suggest that the C 1s spectra can be quantitatively analyzed without considering the influences of a when the ratio of α for sp~2 carbon to that for sp~3 carbon [α(sp~2): α(sp~3)] is between 10:0 and 5:5. The distribution in the α ratio may indicate that the sp~2 and the sp~3 carbon atoms can interact with each other (hybridization) and differ from those highly oriented pyrolytic graphite and diamond, respectively.
