In this paper, we focus on the cause of the variation in the thermoelectric figure of merit of n-Bi{sub 2}Te{sub 3} samples. Relatively moderate values of the thermoelectric figure of merit Z{sub max} in single crystals of n-Bi{sub 2}Te{sub 3}(Te), grown by the Czochralski technique from the tellurium-rich melt (nominal composition of the starting charge, 64.6 at % Te), result from a nonoptimal carrier concentration associated with an insufficient content of tellurium incorporated in the alloy matrix upon crystallization from the melt as well as from the presence of tellurium in the form of a distinct phase.
