Abstract

Homogeneous and graded n- and p-type (Bi<sub>2</sub>Te<sub>3</sub>)<sub>1-x-y</sub>(Sb<sub>2</sub>Te<sub>3</sub>)<sub>x</sub>(Sb<sub>2</sub>Se<sub>3</sub>)<sub>y</sub> crystals are grown by the Czochralski technique with melt supply through a floating crucible. The dimensionless thermoelectric figure of merit of the n- and p-type crystals is ZT = 1.1 (350 K) and 1.0 (375 K), respectively. It is shown that (Bi<sub>2</sub>Te<sub>3</sub>)<sub>1-x-y</sub>(Sb<sub>2</sub>Te<sub>3</sub>)<sub>x</sub>(Sb<sub>2</sub>Se<sub>3</sub>)<sub>y</sub> pseudoternary solid solutions can be used to produce monolithic n- and p- type graded and segmented thermoelectric materials by Czochralski growth. The thermoelectric power distribution across the seed-crystal interface is studied using scanning hot microprobe measurements.
