摘要：
n-type Bi2(Te0.90Se0.10)3/(SiC)y (0 ≤ y ≤ 0.01) composites with nano-SiC were fabricated by mechanical alloying combined with microwave sintering. The microstructure and thermoelectric properties of Bi2(Te0.90Se0.10)3/(SiC)y were studied systematically. The nano-SiC particles as the phonon scattering center uniformly distributed in the matrix, with little effect on the electric transport performance and significantly reducing the thermal conductivity of n-type Bi2(Te0.90Se0.10)3/(SiC)y (0 ≤ y ≤ 0.01). The introduction of nano-SiC optimizes the thermoelectric performance, and the sample with SiC y = 0.0075 obtains the highest ZT~0.94 at 323 K.
