Weak Electron-Phonon Coupling and Enhanced Thermoelectric Performance in n-type PbTe-Cu2Se via Dynamic Phase Conversion

Ming Wu et al.

Summary: This study investigates the effects of Ga-doped n-type PbTe thermoelectric materials and Cu2Se alloying. The introduction of Cu2Se enhances the electrical transport properties and reduces the lattice thermal conductivity. Cu2Te and CuGa(Te/Se)2 nanocrystals precipitate during the alloying process, which increase the carrier concentration and electrical conductivity. With increasing temperature, the sample exhibits a dynamic change in Cu2Te content and the generation of a new phase of CuGa(Te/Se)2, resulting in an ultralow lattice thermal conductivity. The Pb0.975Ga0.025Te-3%CuSe sample demonstrates promising thermoelectric performance for intermediate-temperature device applications.

Enhancement of Thermoelectric Performance for InTe by Selective Substitution and Grain Size Modulation

Menghui Zhou et al.

Summary: The selective substitution of In+ by Pb in the binary InTe material reduces the carrier concentration and helps investigate the mechanism of grain boundary scattering. The dominant factor of grain boundary scattering changes from grain size to carrier concentration depending on the carrier density. Pb occupation on the targeted In+ site further reduces the lattice thermal conductivity. In0.9999Pb0.0001Te achieves improved power factor and average zT value for high-power generation at medium temperatures. Increasing carrier concentration suppresses grain boundary scattering and improves electron mobility.

Carrier grain boundary scattering in thermoelectric materials

Chaoliang Hu et al.

Summary: Bulk nanostructuring has been a leading strategy for optimizing thermoelectric properties by introducing strong grain boundary scattering, but recent findings have shown that charge carrier transport in some nanostructured materials can be significantly suppressed. Understanding the interaction mechanism of grain boundaries on carrier transport and strategies to enhance thermoelectric performance are crucial. Additionally, using the charge shielding ratio as an indicator to distinguish between different scattering mechanisms is proposed.

Thermoelectric Zintl Compound In1-xGaxTe: Pure Acoustic Phonon Scattering and Dopant-Induced Deformation Potential Reduction and Lattice Shrink

Fan Li et al.

Summary: We report a new Zintl phase thermoelectric material with a peak ZT value of 1.2 at 648 K and an average ZT value of 0.8 in the temperature range of 300-650 K, which outperforms all known InTe-based materials to date. The synergistic optimization of electronic property and phonon transport are achieved through the purification of grain boundary scattering and Ga-doping-induced weak phonon-electron coupling, resulting in enhanced carrier mobility and concentration, leading to a significantly increased power factor.

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.

The role of electronic affinity for dopants in thermoelectric transport properties of InTe

Huaxing Zhu et al.

Summary: Cu doping is found to be more favorable for the transport properties of InTe compared with Na doping and In-deficiency, as Cu can effectively weaken the Coulomb scattering for charge carriers. In the case of Cu-doped In0.99Cu0.01Te compound, a higher zT value is achieved, attributed to the enhanced carrier concentration and well-maintained mobility, showing more than 35% enhancement compared to Na-doped and self-doped compounds.

Synthesis and physical properties of single-crystalline InTe: towards high thermoelectric performance

Shantanu Misra et al.

Summary: Chalcogenide semiconductors and semimetals, including tetragonal InTe, are promising candidates for thermoelectric applications due to their high thermoelectric performance near 800 K. An investigation of InTe single crystals grown over a wide temperature range revealed anisotropic transport coefficients and a semiconductor ground state despite previous suggestions of a semimetallic nature. The extremely low lattice thermal conductivity of InTe, combined with a relatively high power factor, resulted in a maximum dimensionless thermoelectric figure of merit of 0.61 at 780 K along the [110] direction, laying a solid foundation for future doping strategies in high-temperature thermoelectric applications.
