Abstract

Iron impurities on interstitial (Fei) and substitutional sites (FeS) in SiC have been detected by 57Fe emission Mössbauer spectroscopy following implantation of radioactive 57Mn+ parent ions. At temperatures <900 K two Fei species are found, assigned to quasi-tetrahedral interstitial sites surrounded by, respectively, four C (Fei,C) or Si atoms (Fei,Si). Above 900 K, the Fei,Si site is proposed to “transform” into the Fei,C site by a single Fei jump during the lifetime of the Mössbauer state (T 1/2 = 100 ns). Fei,C and substitutional FeS sites are stable up to >1,070 K.
