Abstract
The compounds (Au,Ag)Te2 exhibit remarkable modulated structures of different types, depending on the exact ratio of the concentrations of gold and silver. Calaverite (AuTe2) has a deformation modulated structure, which in the case of non-stoichiometric Sylvanite (Au1+x Ag1−x Te4) is moreover coupled with a long period anti-phase boundary superstructure. Finally in Krennerite (Au0.8 Ag0.2 Te2) the structure is modulated by poly-synthetic twinning. In all cases the modulation planes are approximately along the (101) planes of calaverite. The modulation periods are also approximately of the same magnitude in the different cases.
