Constructed Ge Quantum Dots and Sn Precipitate SiGeSn Hybrid Film with High Thermoelectric Performance at Low Temperature Region

Ying Peng et al.

Summary: SiGe-based thermoelectric materials are traditionally known for high-temperature applications, but this study demonstrates the successful construction of Ge quantum dots and Sn precipitation SiGeSn hybrid films via ultrafast high temperature annealing. By combining modulation doping dominated by Sn precipitates and energy filtering caused by Ge QDs, the optimized SiGe films achieve a giant power factor of 91 mu W cm(-1) K-2 @300 K at room temperature, while maintaining low thermal conductivity. This novel film construction strategy offers insight for TE materials with impressive performance.

Achieving high thermoelectric performance through carrier concentration optimization and energy filtering in Cu3SbSe4-based materials

Sitong Wei et al.

Summary: In this study, Cu3SbSe4/TiO2 hollow microspheres were synthesized using a microwave-assisted hydrothermal synthesis method. The doping of Ti was found to significantly change the band structure and phonon spectrum, leading to the regulation of carrier concentration and increased phonon scattering. The incorporation of TiO2 nanoparticles also resulted in an energy filtering effect that suppressed the decrease of the Seebeck coefficient. As a result, the Cu3SbSe4/6%TiO2 sample exhibited the highest average power factor and peak zT value.

Synergistic Effect of Work Function and Acoustic Impedance Mismatch for Improved Thermoelectric Performance in GeTe-WC Composite

Ashutosh Kumar et al.

Summary: This study demonstrates the enhanced thermoelectric performance of a composite material by manipulating its composition and acoustic impedance mismatch. The increase in electrical conductivity and Seebeck coefficient results in a higher power factor, while the difference in elastic properties leads to a large interface thermal resistance and reduced phonon thermal conductivity. The simultaneous effect of enhanced electrical parameters and reduced thermal conductivity provides a promising strategy for achieving higher thermoelectric figure of merit. Through detailed analysis of electrical properties and thermal transport, this study provides insights for the design and optimization of thermoelectric materials.
