TL;DR: The pseudo ternary phase diagram for Cd-Bi/Sb-Te in the region near (Bi,Sb)2Te3 was systematically studied, which proves that Cd serves as an acceptor dopant contributing holes, whereas for samples doped with CdTe, the combined effects of the substitution of Sb/Bi with Cc leads to increase hole concentration.

TL;DR: In this article, a series of Bi2Te2-xS1+x compounds were prepared by traditional melting-quenching-annealing process, and the results showed that the strong coupling of the phonon density of state contributed by Bi and Te(1) atoms results in the low avoided-crossing frequencies, sound velocities, Debye temperature and therefore the low lattice thermal conductivities.

TL;DR: In this article, the influence of Sn and Ge doping on the structure and thermoelectric properties of p-type Bi2Te3-based materials is systematically studied, and the authors obtain a maximum power factor of 3.8mWm−1K−2

TL;DR: In this paper , the influence of Sb dopant on the thermoelectric properties of PbTe compounds was systematically investigated by using a phase boundary method, and the authors obtained a large power factor of 19 μW/cm/K2 at room temperature and a maximum power factor for Pb 0.99Sb0.01Te at 573 K.

TL;DR: In this article, a reproducible improvement of the thermoelectric performance in BiSbTe alloy via kinetically and dynamically regulating excitation behavior in the intrinsic excitation regime was reported.
