resulting in The common principle of scanning the Seebeck material is based on simultaneous measurement of two thermo-voltages, caused by a temperature

Homogeneous and graded n-and p-type (Bi 2 Te 3 ) 1 -x -y (Sb 2 Te 3 ) x (Sb 2 Se 3 ) y 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 2 Te 3 ) 1 − x -y (Sb 2 Te 3 ) x (Sb 2 Se 3 ) y pseudoternary solid solutions can be used to produce monolithic n-and ptype graded and segmented thermoelectric materials by Czochralski growth. The thermoelectric power distribution across the seed-crystal interface is studied using scanning hot microprobe measurements.
