摘要：

Polarized Raman spectra have been performed in keV ion irradiated highly oriented pyrolytic graphite in order to investigate the disorder induced by energetic ions in the carbon matrix at room temperature. Early stages of ion irradiation (10(12)-10(15) He+/cm2 3 keV) induce a high depolarization ratio of the 1360 cm-1 D line, leaving the 1580 cm-1 line almost unchanged. This was interpreted by an anisotropic damage induced in the highly oriented pyrolytic graphite structure by an ion collision cascade.
