Characterization of carbon films on the Japanese smoked roof tile'Ibushi-Kawara' by high-resolution soft X-ray spectroscopy
Carbon films on the Japanese smoked roof tile ''Ibushi-Kawara'' were characterized by high-resolution soft X-ray spectroscopy using synchrotron radiation. By comparing the soft X-ray emission and absorption spectra of Kawara with the reference carbon compounds, it was determined that the carbon films on Kawara consist of mostly carbon-black-like sp2 carbon atoms and that the surface also contains polyethylene-like sp3 carbon atoms. The take-off/incident-angle dependence on the X-ray emission/absorption spectra of Kawara shows that the carbon-black-like sp2 carbon atoms partially form a layer structure oriented parallel to the basal clay plane, and that the degree of orientation of the carbon films is estimated to be 50 percent that of highly oriented pyrolytic graphite (HOPG). The microstructure of the carbon films on Kawara is one in which half of the carbon-blacklike sp2 carbon atoms form layer-structured clusters parallel to the basal clayplane and the rest of the carbon atoms form random-structured clusters which rigidly connect the layer-structured clusters.
