Abstract content <br> &nbsp; (Max 300 words)

The study of ion beam modification of surfaces has increasingly become an integral part of characterising silicon carbide and related nuclear materials. The effect of a relatively high fluence (2 x 10^{17 127}I⁺ ions) of iodine on the surface of 6H-SiC has been investigated. The contribution of vacuum annealing to the evolution of the surface morphology was also studied. Isochronal vacuum annealing was perfomed at temperetures ranging from 350 °C to 1200 °C. Atomic force microscopy (AFM) and high resolution scanning electron microscopy (FEG SEM) were employed to analyse the surface microstructure.
