摘      要：Thermoelectric(TE)materials and devices have attracted great attention due to their ability to convert waste heat to electrical power and active ***,the conventional bulk TE materials are inorganic semiconductors with inherent brittleness and *** cannot closely contact curved heat sources and sinks,which limits their application in modern *** remains a big challenge to fabricate high-performance TE materials and devices with good ***,we report a flexible TE device comprised of a single wall carbon nanotube(SWCNT)network and(0001)-textured Bi_(2)Te_(3)nanocrystals prepared by a magnetron sputtering *** unique Bi_(2)Te_(3)-SWCNT hybrid structure has a TE figure of merit(ZT)value of^0.23 at^330 K.A prototype TE device made of this hybrid gives a maximum output power density of^0.93 m W cm^(-2)under a temperature difference of 25 K at ambient temperature and shows good flexibility under *** results open up a new way to the development of flexible TEs and their application in self-powered portable devices.
