STUDIES ON NEON IRRADIATED AMORPHOUS CARBON USING X-RAY DIFFRACTION TECHNIQUE

Abstract

Two sets of amorphous carbon materials prepared at different routes are irradiated with swift (145 MeV) heavy ion ( Ne 6+). The structural parameters like the extent of local ordering along the c and a axis i.e., Lc and La, the average spacing of the crystallographic planes (002) i.e., d002 and the fraction of the amorphous phase of the unirradiated and the irradiated samples are estimated by X-ray diffraction technique. The fraction of the amorphous phase is generally found to increase with the irradiation dose for both sets of the samples. The estimated d002 values are found to be almost unaffected by irradiation but Lc and La are decreased slightly with irradiation. The estimated values of Lc and La corroborate with the increase of disorder in both sets of the samples with the increasing dose of irradiation.
