Achieving metal-like malleability and ductility in Ag₂Te_1-x S _x inorganic thermoelectric semiconductors with high mobility.

ABSTRACT: Inorganic semiconductor Ag₂Te_1-x S _x has been recently found to exhibit unexpected plastic deformation with compressive strain up to 30%. However, the origin of the abnormal plasticity and how to simultaneously achieve superb ductility and high mobility are still elusive. Here, we demonstrate that crystalline/amorphous Ag₂Te_1-x S _x (x = 0.3, 0.4, and 0.5) composites can exhibit excellent compressive strain up to 70% if the monoclinic Ag₂Te phase, which commonly exists in the matrix, is eliminated. Significantly, an ultra-high tensile elongation reaching 107.3% was found in Ag₂Te_0.7S_0.3, which is the highest one yet reported in the system and even
