Thermoelectric Performance Enhancement in BiSbTe Alloy by Microstructure Modulation via Cyclic Spark Plasma Sintering with Liquid Phase

Hua-Lu Zhuang et al.

Summary: The study emphasizes the importance of the synthesis process for achieving high performance in Bi2Te3-based thermoelectric materials. By applying cyclic spark plasma liquid phase sintering, a unique microstructure with enlarged grains and abundant nanostructures can be formed, leading to high charge carrier mobility and low lattice thermal conductivity. This results in a significantly higher ZT value compared to conventionally spark-plasma-sintered materials.

Realizing p-type Mg2Sn Thermoelectrics via Ga-Doping and Point Defect Engineering

Zhicheng Huang et al.

Summary: The addition of Ga as a dopant in Mg2Sn can change its conduction type from n-type to p-type, leading to an increase in the magnesium vacancy fraction and the introduction of hole carriers. This doping strategy results in a lower total thermal conductivity at a certain concentration, contributing to the improvement of thermoelectric material performance.

Optimization of the Thermoelectric Properties of p-Type Mg2-yLiyGe1-xSnx and Mg2-yLiyGe1-zSiz with x, z=0.1 and 0.2

Vidushi Galwadu Arachchige et al.

Summary: Recent investigations have found that p-type Mg2Ge exhibits superior thermoelectric properties compared to p-type binaries. By alloying Si or Sn into the Ge site, further optimization can be achieved to lower thermal conductivity. Samples rich in Ge show similar temperature-dependent behavior in electronic properties to p-type Mg2Ge, while samples containing Si have achieved the highest reported figure of merit so far in the p-type Mg-2(Ge,Si) systems.
