Abstract

Diamond, silicon and germanium have the diamond structure. Hence these three elements were chosen to make a comparative study of their behaviour when damaged by heavy ions under the same conditions. Bulk damage of diamond was studied in detail by M. M. Sarkar in 1984. Powdered samples of germanium and silicon were prepared in the laboratory of Marquette University Physics Department. X-Ray diffraction analysis and SEM photographic analysis of the samples were also made. Heavy ion bombardment was done at Argonne National Laboratory using the dynamitron. Due to the faulty functioning of the dynamitron the original plan was abandoned and very little was undertaken on diamond. Whatever information that could be gathered from the study of the other two elements, has been collected in ' this thesis with the hope that it may prove useful to any future attempt along these lines. The area density experiments were conducted only on silicon. The annealing behaviour of germanium produced some results; silicon could not be annealed under the available conditions. Thus the only comparative study of the elements were the x-ray diffraction studies of the samples before and after damage.
