Abstract

We present studies of muonium behaviour in bulk, Czochralski-grown Si 1-xGex alloy material, focusing in particular on the hyperfine parameter of the tetrahedral muonium species. In contrast to the bond-centred species, the hyperfine parameter of the tetrahedral-site muonium centre (MuT) appears to vary non-linearly with alloy composition. The temperature dependence of the MuT hyperfine parameter observed in low-Ge alloy material is compared with that seen in pure Si, and previous models of the MuT behaviour in Si are discussed in the light of results from Si1-xGex alloys.
