(a) Red circle solid line represent thermal conductivity of SPS Bi85Sb15 without an applied magnetic field measured using the hot disk method. Blue symbols represent the thermal conductivity calculated using Wiedemann–Franz law assuming that the sample is measured in a magnetic field of 3 kOe. Green dashed line represent the reference data for the polycrystalline averaged single crystal measurements on Bi85Sb15 reported by Yim and Amith. (b) The dimensionless figure of merit, ZT, are obtained using the thermal conductivity results shown in (a) and the electrical resistivity and thermopower data from Figs 5 and 10.
