cze	Termoelektrické vlastnosti kvaternárních monokrystalů (Bi0,25Sb0,75)2-xInxTe3	Tento článek pojednává o vlivu malých koncentrací In na termoelektrické vlastnosti ternárního systému (Bi0,25Sb0,75)2Te3 . Bylo zjištěno, že indium významně zvyšuje koeficient termoelektrické účinnosti zejména v nízkých teplotách.
eng	Thermoelectric properties of quaternary (Bi0,25Sb0,75)2-xInxTe3 single crystals	Crystals of a quaternary system based on (Bi0,25Sb0,75)2Te3 doped with In were prepared using the Bridgman technique. Samples with varying content of In were characterized by the measurements of electrical conductivity c, Hall coefficient RH(B\|\|c), Seebeck coefficient (Tc) and thermal conductivity  (Tc). The temperature dependence of the thermoelectric figure of merit Z=2/ of the samples is further discussed. It was observed that low concentrations of In atoms in the (Bi0,25Sb0,75)2Te3 crystal lattice result in a substantial increase in the parameter Z in the temperature region 100 - 300K.	chalcogenides;crystal growth; thermoelectric properties
