摘要：
The purpose of this work was to investigate the possibility of improving the thermoelectric properties of the metal-ceramic composite Bi2Te3 + 0.5 at. % Gd. It was established that spark-plasma sintering of the initial Bi2Te3 and Gd powders does indeed form the microstructure of the composite, represented by Ni inclusions randomly distributed inside the polycrystalline matrix of Bi2Te3. The resistivity of Bi2Te3 increases and the full thermal conductivity decreases on the addition of Ni filler. The composite’s maximum thermoelectric Q (about 0.63) turns out to be somewhat higher than that of the matrix material (about 0.58).
