Doppler broadening S-parameter measurements have been performed to study Au cluster ion irradiation effects on Fz-Si single crystals by using slow positron beam apparatus. As a result, the depth profile of Doppler broadening S-parameter clearly shows that vacancy type defects are introduced in both irradiation cases, but different types of defects, such as gold-vacancy and vacancy-impurity complexes, are produced in Fz-Si by Au and Au cluster ion irradiation.
