Une surstructure de α-Ge, type diamant, induite par un dopage d'antimoine
Abstract : Single crystals of anti-mony-doped germanium, Ge Sb ( ≃ 0.0625), were grown by chemical transport reaction. The alloy crystallizes as a superstructure of diamond-type α-Ge. All atoms in the asymmetric unit lie on special positions and are characterized by strong covalent bonds. The anti-mony atoms substitute for one germanium atom at full occupancy at Wyckoff position 4 (site symmetry -43), and are also at an adjacent tetra-hedral inter-stitial site with partially occupation (16%) at position 4 (or 4) (site symmetry -43). The structural model does not show close Sb⋯Sb contacts, and suggests that the inter-stitial anti-mony atoms move between the two adjacent tetra-hedral sites.
