Tunable electronic properties and low thermal conductivity in synthetic colusites Cu{sub 26−x}Zn{sub x}V{sub 2}M{sub 6}S{sub 32} (x ≤ 4, M = Ge, Sn)

We have first synthesized Cu{sub 26−x}Zn{sub x}V{sub 2}M{sub 6}S{sub 32} (x ≤ 4, M = Ge, Sn) with the cubic colusite structure and measured the thermoelectric properties. For both M = Ge and Sn, the samples with x = 0 show moderately large thermopower of +27 μV/K at 300 K. The metallic conduction of...
