Abstract: The effect of dendritic inhomogeneity in Bi$_{0.88}$Sb$_{0.12}$ crystals on the transport properties and thermoelectric Q-factor was studied by experiment. It was found that the thermoelectric Q-factor of dendritic Bi$_{0.88}$Sb$_{0.12}$ crystals grown at a molten zone displacement rate of 1 cm/h exceeds the Q-factor of homogeneous crystals of the same composition by up to 20%.

Keywords: bismuth, antimony, dendritic inhomogeneity, thermoelectric properties.
