Abstract

The effect of dendritic inhomogeneity in Bi_0.88Sb_0.12 crystals on the transport properties and thermo electric Q-factor was studied by experiment. It was found that the thermoelectric Q-factor of dendritic Bi_0.88Sb_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%.
