Abstract: We report on the lattice location of Er in Si using the emission channeling technique. The angular distribution of conversion electrons emitted by the decay chain Tm-167 (t(1/2=)9.25 d) --> Er-167m (2.27 s) was monitored with a position-sensitive detector following room temperature implantation and annealing up to 950 degrees C. Our experiments give direct evidence that Er is stable on tetrahedral interstitial sites in float-zone Si. We also confirm that rare earth atoms strongly interact with oxygen, which finally leads to their incorporation on low-symmetry lattice sites in Czochralski Si.
