| Zusammenfassung | We present a study of excitons bound to sulfur- and copper-related isoelectronic centres in highly enriched 28Si. The S-related centre, which has been shown to have two configurations, SA and SB, was believed to consist of a substitutional sulfur atom paired with an interstitial copper atom. High resolution photoluminescence (PL) emissions from the no-phonon SB0 transition reveal fine structure no observable in natural silicon. In both 28 Si:natS and 28Si:34S, low temperature PL reveals at least 18 distinct components of the SB0 system, including a triplet splitting seen in natSinatS by optical detection of magnetic resonance. Investigation of the effect of copper isotopic composition on the SB0 system shows that the centre contains at least three copper atoms. We also present results on the copper isotope effect on the 943.7 meV *Cu00 system in 28Si and show that three Cu atoms contribute to the Cu isotope shift of *Cu00. |
