Abstract

Mineral calaverite AuTe₂ is a layered compound with an incommensurately modulated structure. The modulation is characterized by the formation of molecular-like Te₂ dimers. We have found that the breaking of Te₂ dimers that occurs in Au_1-xPt ^xTe² results in the emergence of superconductivity at T_c = 4:0 K.
