Abstract Sintered carbon nanotube (CNT) blocks and porous CNT sponges were prepared, and their thermoelectric properties were measured. The maximum dimensionless thermoelectric figure-of-merit, ZT, at room temperature of the sintered single-walled carbon nanotube (SWCNT) block is 9.34 × 10−5, which is twice higher than that of the sintered multi-walled carbon nanotube (MWCNT) block in this work and also higher than that of other sintered MWCNT blocks reported previously. In addition, the porous MWCNT sponge showed an ultra-low thermal conductivity of 0.021 W/(m K) and significantly enhanced ZT value of 5.72 × 10−4 at room temperature and 1 atm. This ZT value is higher than that of other 3D macroscopic pure CNT materials reported. The pronounced enhancement of the ZT in the porous MWCNT sponge is attributed to the ultra-low density, ultra-high porosity, and interconnected structure of the material, which lead to a fairly low thermal conductivity and better Seebeck coefficient. The finding of this work provides an understanding for exploring potential enhancement mechanisms and improving the thermoelectric properties of CNT-based thermoelectric composites.

Методами физико-химического анализа – дифференциально-термическим, высокотемпературным дифференциально-термическим, рентгенофазовым, микроструктурным, а также измерением микротвердости изучена система Sm2Te3–GeTe, которая является квазибинарным сечением тройной системы Ge–Sm–Te. При соотношении исходных теллуридов 1:1 (50 мол. %) и температуре 1100 К по перитектической реакции ж+Sm2Te3→ GeSm2Te4 образуется тройное соединение GeSm2Te4. Образцы системы, богатые GeTe, представляют собой компактные слитки блестяще-серого цвета, а сплавы, бо-гатые Sm2Te3 – спек черного цвета. Ликвидус системы Sm2Te3–GeTe состоит из трех ветвей: Sm2Te3, GeSm2Te4 и a-твердых растворов на основе GeTe. Рентгенофазовый анализ закристаллизованных образцов показал, что набор рентгеновских отражений соответствует фазам Sm2Te3, GeSm2Te4 и a-твердых растворов на основе GeTe. Установлено образование инконгруэнтно плавящегося соединения состава GeSm2Te4, которое может использоваться как термоэлектрический материал.
