We have studied the effects of structural vacancies on the thermoelectric properties of the ternary compounds (Cu₂Te)1–x(Ga₂Te₃)x (x=0.5, 0.55, 0.571, 0.6, 0.625, 0.667 and 0.75), which are solid solutions found in the pseudo-binary phase diagram for Cu₂Te and Ga₂Te₃, and possesses tunable structura...
