Abstract:	The effect of 100 MeV irradiation of iron ions in p-type gallium antimonide for ion fluences varying from 1 x 10(11) to 5 x 10(13) cm(-2) was investigated using Raman scattering, Fourier transform infrared and X-ray diffraction measurements. Raman spectra showed a strong peak at 232.82 cm(-1) (LO) and a weak peak at 223.79 cm(-1) (TO). The peaks were shifted towards higher wave number compared to non-irradiated sample indicating the presence of stress in the irradiated samples. The increase of optical absorbance of samples irradiated with different fluences indicates the increase in the amount of disorder and defect concentrations with fluence. The intensity of the XRD peak (20 = 61.07 degree) of the irradiated samples for (4 0 0) reflections was found to decrease with ion fluence. (c) 2008 Elsevier B.V. All rights reserved.
