Here we show the high-temperature thermoelectric (TE) properties of Cu2Ga4Te7 with the defect zinc-blende structure in which one-seventh of the cation sites are structural vacancies. Cu2Ga4Te7 exhibited relatively low electrical resistivity (rho) and thermal conductivity (kappa) and moderate positive Seebeck coefficient (S) at high temperatures, making this compound a promising high-performance p-type TE material. At 940 K, the S, rho, and kappa were +215 mu V K-1, 10.1 X 10(-5) Omega m, and 0.67 Wm(-1) K-1, respectively, which resulted in the maximum dimensionless figure of merit ZT (=(ST)-T-2/rho/kappa, where T is the absolute temperature) of 0.64.
