“…In accordance with the studies discussed in the introduction [11][12][13][14][15], we found a large fraction of the TMs on the S site in Ge after ion implantation. The prevalence of the S site is consistent with theoretical work [15,16] where the S site was found to be more favourable than the T and H sites.…”

“…However, the full picture seems to be more complicated. From Mössbauer spectroscopy experiments after recoil implantation of 57m Fe and ion implantation of 57 Mn in Ge, the Fe-atoms were found to occupy the S site, but also the T site and a third site believed to be related to Fe i -V complexes [12,13]. From emission channeling experiments similar to the ones presented here, a large fraction of ion implanted 67 Cu was found on the S site, together with a smaller fraction located halfway between the S and the bond-centered (BC) site [14].…”

Transition Metal Impurities on the Bond-Centered Site in Germanium

We report on emission channeling experiments on ion implanted Fe, Cu and Ag impurities in germanium and ab initio total energy calculations. Following common expectation, a fraction of these transition metals was found on the substitutional Ge position. Less expected is the observation of a second fraction on the 6-fold coordinated bond-centered site. Ab initio calculated heats of formation suggest that this is the result of an impurity-vacancy defect complex in the split-vacancy configuration.
