Abstract
The deep level transient spectroscopy technique has been applied to silicon doped with radioactive impurities. The disappearance or appearance of features in the spectra following the transmutation of the incorporated radioactive atoms identifies an impurity involved in the centers observed. Results for Au and Pt diffused in Si are presented showing that Au occupies the same lattice position as Pt, which is known from electron paramagnetic resonance measurements to be substitutional.Keywords
