Svechnikova, L. Shelimova, P. Konstantinov, M. Kretova, E. Avilov, V. Zemskov, C. Stiewe, E. Müller] Thermoelectric materials for segmented n-and p-legs of thermoelectric generators have been prepared by Czochralski growth with melt supply through a floating crucible. Two-segment ingots have been obtained using melt compositions corresponding to ternary layered compounds in the PbTe-Bi2Te3 and PbTe-Sb2Te3 systems, with (Bi2Te3)1−x−y (Sb2Te3) x (Sb2Se3) y solid solutions as seed materials. Seeded growth of the ternary compounds makes it possible to fabricate legs without joining segments by soldering. Using scanning hot point microprobe measurements, we have studied the thermoelectric power distribution across the seed-crystal interface. The results attest to a steep thermoelectric power gradient across the seed-crystal interface in a narrow region. Quantitative analysis of the distribution of the number of measurements with respect to thermoelectric power has revealed peaks corresponding to individual segments.
