초록
We have carried out spectroscopic studies on the physical properties of graphite tiles modified by electron and proton irradiation. While increase in local order was observed in the electron-irradiated sample, structural disorder and amorphization were revealed in the proton-irradiated sample, with considerably decreased electrical conductivity. Besides, C-OH bond with a sp3 configuration was identified in the proton-irradiated sample, apparently giving rise to a narrow ESR peak ascribed to localized spins.
