Abstract: This article investigates the effect of aluminum doping on the thermal conductivity and other thermoelectric properties of nanostructured Zn1•XAlXTe (0 ≤ X ≤ 0.15) for a temperature range of 300 K – 600 K. The thermal conductivity was measured using the transient plane source (TPS) technique by a Hot Disk thermal constants analyzer. It was found that with increasing doping of aluminum, the thermal conductivity decreased, and with increasing temperature thermal conductivity also decreased. The decreasing of thermal conductivity increased the performance of the thermoelectric material expressed by the dimensionless figure of merit (zT).
