ds-Block Element-Enabled Cooperative Regulation of Electrical and Thermal Transport for Extraordinary N- and P-Type PbSe Thermoelectrics near Room Temperature

Dan Zhang et al.

Summary: This study presents a new strategy to enhance the thermoelectric performance of PbSe materials at near room temperature by introducing ds-block elements. The achieved high thermoelectric performance in both n-type and p-type PbSe is attributed to the synergistic effects of Cu interstitial, Cd alloying, and Ag doping, which optimize the effective mass, carrier concentration, and mobility. The developed PbSe systems show great potential for low-cost thermoelectric devices across a broad temperature range.

Considering the Role of Ion Transport in Diffuson-Dominated Thermal Conductivity

Tim Bernges et al.

Summary: Next-generation thermal management requires the development of materials with low lattice thermal conductivity, such as ionic conductors. However, high ionic conductivity can negatively affect thermoelectric devices. This study shows that high ionic mobility is not a requirement for diffuson-mediated transport, and that the same structural traits that enable fast ionic conduction also lead to diffuson-mediated transport.

Contrasting Cu Roles Lead to High Ranged Thermoelectric Performance of PbS

Yongxin Qin et al.

Summary: By introducing Cu with different roles into p-type PbS, this study effectively reduces lattice thermal conductivity and optimizes electrical transport properties. Experimental results show that Cu substitutions and interstitials can improve carrier mobility and shift the peak power factor to lower temperatures, leading to record-high ZT values. The special dynamic-doping behaviors of Cu continuously promote carrier concentration towards a temperature-dependent relationship, resulting in an eminent average power factor among the tested temperature range.
