摘要：

Real-time Raman measurements have been performed on graphite under 3-keV Ar+-ion irradiation with a time resolution of 6 sec. Ion flux of 3 x 10(11) and 4 x 10(10) ions/cm2 sec are used. The graphite lattice damage is estimated by the relative intensity ratio of the disorder-induced peak (approximately 1360 cm-1) with respect to the Raman-active E2g-mode peak (approximately 1580 cm-1). The relative intensity change in the Raman spectrum caused by the irradiation is explained in terms of a reduction in the phonon correlation length due to defects.
