Summary: Defect engineering, achieved by precise tuning of atomic disorder, can significantly enhance thermoelectric performance. The introduction of Hg doping into AgSbTe2 reduces structural disorder, increases carrier mobility, and lowers lattice thermal conductivity. A high thermoelectric figure-of-merit, zT, is achieved at 570K.

Summary: Nanostructuring is an effective approach to improve the thermoelectric behavior of materials. However, the effectiveness is limited if excessively small particle sizes are necessary to decrease the lattice thermal conductivity. This study combines ab initio calculations and machine learning to systematically investigate the thermoelectric properties of nanostructured AgInTe2, showing that ZT values up to 2 can be achieved at 700 K with an average grain size in the range of 10-100 nm.

Summary: This study investigates the ballistic thermoelectric properties of T-HfSe2 nanoribbons using ab initio calculations based on density functional theory and the Landauer formalism. The structural symmetry affects the n-type Seebeck coefficient and power factor, while the p-type thermoelectric coefficients are not significantly influenced. Phonon thermal conductance is reduced via nanostructuring.

Summary: In this study, a fast preparation method of self-propagating high-temperature synthesis was used to realize in situ compositing of BiCuSeO and Cu2Se, optimizing the service stability of the thermoelectric materials. Additionally, the introduction of graphene in the composites improved the carrier mobility and reduced lattice thermal conductivity. The Cu2Se-BiCuSeO-graphene composites exhibited excellent thermoelectric properties.

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: 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: Crystal-phase engineering is an effective method for modulating the properties and functions of semiconductor materials, but it has rarely been explored in thermoelectrics. In this study, nanostructured solids with unconventional cubic-phase are prepared through ligand retention using a combined colloidal synthesis and sintering route. The unconventional cubic-phase samples show optimized electrical and thermal properties through phase and entropy design.
