Summary: In-single-filled InxCo4Sb12 skutterudite with high density was synthesized by microwave heating and subsequent annealing and spark plasma sintering. The microstructure characteristics, such as pores and dislocations, were observed, which contribute to the reduction of lattice thermal conductivity. Indium atoms optimize the carrier concentration and InSb acts as an effective dopant. The highest ZT value of 1.15 was achieved at 773 K.

Summary: This research proposes a C-8-BTBT molecule displaced by an intermediate layer for single-molecular junctions, showing low phonon thermal conductance. Additionally, doping with p/n-type electrodes effectively tunes both electronic and phononic transport properties to enhance power factor and thermoelectronic figure-of-merit significantly. Reducing mass mismatch in electrode structure and boron/nitrogen doping play key roles in increasing phonon thermal conductance and improving thermoelectronic figure-of-merit.

Summary: In this work, a high ZT value (>1.3) is achieved in Bi0.90Pb0.10Cu0.96Fe0.04SeO fabricated via microwave synthesis and spark plasma sintering. By adding Fe to the Pb-doped BiCuSeO, the hole carrier concentration and mobility are regulated, resulting in moderate electrical conductivity, high Seebeck coefficient, and low carrier thermal conductivity. The lattice thermal conductivity of Bi0.90Pb0.10Cu0.96Fe0.04SeO is limited to a low range (0.24-0.49 W m(-1) K-1) due to synergistic enhancement by stress field, dislocation, and nanophase.

Summary: Here we report a study on compositing highly conductive GdH2 with BiCuSeO to modulate the electronic transport and conductivity at high temperatures. The incorporation of GdH2 as a minor matrix in BiCuSeO significantly improves the electrical conductivity of the system, indicating the presence of thermal activation of charge carriers. The addition of the minor matrix directly converts the p-type conductivity of BiCuSeO to n-type conductivity at near room temperature. Ambiguities in transport behavior at near room temperature are identified by the electronic quality factor (B-E). The power factor is enhanced by GdH2, with a highest attained value of 221 mu W m K-2 at 700 K for the sample with x = 11 wt%, which is nearly twice the value of pristine BiCuSeO. The highest ZT of 0.011 is obtained for the pristine BiCuSeO sample at 380 K.

Summary: Nearly single-phase Bi1-xCaxCuSeO bulks were fabricated via 4 min microwave synthesis combined with 5 min spark plasma sintering (SPS). The effect of Ca doping on the thermoelectric performance was studied, and it was found that the conductivity and power factor increased with increasing Ca concentration due to the increase in carrier concentration and mobility. The two-dimensional layered superlattice structure resulted in relatively low lattice thermal conductivity, leading to enhanced thermoelectric performance.

Summary: In this study, Ag-deficient Ag2Se was prepared using a hydrothermal method and hot-press densification process, and the effect on thermoelectric properties was investigated. The research found that increasing the Ag content led to an increase in the calculated density of states effective mass (m*), resulting in an enhanced maximum zT of 0.43 at 393 K for Ag1.99Se. Furthermore, the complex nanostructures including grain boundaries, nanograins, and lattice distortions in Ag2-xSe contributed to reduced thermal conductivity (kappa) in the range of 0.9-1.1 W m(-1) K-1 at 303 K. The aim was to improve the thermoelectric performance of Ag2-xSe for room temperature applications.

Summary: Density functional theory calculations were used to study the thermoelectric properties of phosphorene oxide (PO), revealing superior performance compared to pristine phosphorene. Spontaneous oxidation of phosphorene led to significant enhancement in thermoelectric properties of n-doped phosphorene oxide, attributed to reduced lattice thermal conductivity while maintaining electrical conductivity. These findings suggest that controlling oxidation could improve thermoelectric performance in nanostructures, with PO being a promising candidate for low-dimensional thermoelectric devices.

Summary: In this study, Ag2Te nanoparticles were synthesized using the hydrothermal method, showing significant improvement in thermoelectric properties compared to the bulk Ag2Te sample. Ag2Te nanoparticles exhibited the highest figure of merit (zT) of 1.37 at 373 K, which is the highest reported for this undoped material. The high zT in Ag2Te nanoparticles is attributed to the approximately 2 times higher electrical conductivity and subsequently 2 times lower thermal conductivity compared to the bulk sample.

Summary: Configurational entropy is considered a gene-like performance indicator for thermoelectric materials, but increasing configurational entropy alone does not guarantee a high thermoelectric figure of merit. Therefore, it is necessary to determine protocols for designing medium-and high-entropy thermoelectric materials with high ZT values. In this study, a strategy for designing high ZT n-type ZrCoSb-based medium-entropy half-Heusler alloys is provided, highlighting the tradeoff between alloy composition and amount. The developed design concept enables the medium-entropy half-Heusler alloy to exhibit a high peak ZT of approximately 0.57.

Summary: Mg3Sb2-based Zintl compounds are explored as potential thermoelectric materials due to their natural abundance, low cost, and compatibility with sustainable green technology. However, p-type Mg3Sb2 has lower thermoelectric efficiency compared to its n-type counterpart. By codoping monovalent atoms at the Mg site, such as Li-Ag and Na-Ag, the electrical conductivity and thermoelectric properties of p-type Mg3Sb2 can be enhanced. Among the different doping combinations, Na-Ag codoping is found to be more effective in increasing the charge carrier concentration and electrical conductivity. This study provides a constructive approach to enhance the thermoelectric performance of p-type Mg3Sb2 through monovalent atoms codoping at the Mg sites.
