Description We have investigated the effect of Sb-deficiency on the thermoelectric figure of merit (zT) of Zn4Sb3 prepared by solid state reaction route. At high temperatures, the Seebeck coefficient (S) and electrical conductivity (sigma) increases with increase in Sb deficiency whereas the thermal conductivity (kappa) decreases giving rise to. an increase in the overall zT value. The observations suggest that creation of vacancies could be an effective route in improving the thermoelectric properties of Zn4Sb3 system. (C) 2015 Elsevier Ltd. All rights reserved.
