Abstract

Radioactive119mCd+ and119In+ ions have been implanted into CdTe single crystals at temperatures between 50–300K. Radiogenic defects formed with the daughter119Sn have been investigated by Mössbauer spectroscopy of the emitted 24 keV γ radiation. All Mössbauer spectra could be analysed consistently with three lines. These are proposed to be due to substitutional Sn on Cd sites in two different charge states and to Sn-vacancy complexes. The corresponding In-parent vacancy complexes anneal at 120K and above 300K.
