The low bandgap semiconductor, SnTe is receiving significant attention as a thermoelectric
material because of its low toxicity and environment-friendly nature. In this study, we report
the effect of co-doping dilute concentrations of Ag and Cu ions in SnTe that suppresses the
Sn vacancies leading to optimized thermoelectric properties. Samples of nominal chemical
composition Sn 1.03–2x Ag x Cu x Te (x= 0, 0.01, 0.02, 0.04) were prepared by the solid-
state route. The Rietveld refinement of powder XRD of these compounds showed a fcc (Fm …
