Thermoelectric properties of single crystal Ta2PdSe6 is investigated by means of transport measurements, and a density functional calculation. We found a giant Peltier conductivity of 100 A cm−1 K−1 at 10 K and successfully explained it by means of conventional semiconductor theory. We concluded that an uncompensated semimetal, high mobility, and heavy effective mass are responsible for the giant Peltier conductivity. Our finding opens a new ground in the field of thermoelectrics to explore…

Thermoelectric properties of semimetals
Heavily doped semiconductors are by far the most studied class of materials for thermoelectric applications in the past several decades. They have Seebeck coefficient values which are 2-3 orders of
Nanostructured YbAgCu4 for potentially cryogenic thermoelectric cooling.
TLDR
A peak dimensionless thermoelectric figure-of-merit, ZT, of 0.11 has been achieved at 42 K, which may find potential applications for cryogenic cooling below 77 K.
Antiferroelectric distortion with anomalous phonon softening in the excitonic insulator Ta2NiSe5
Ta2NiSe5 is considered a promising excitonic insulator (EI) candidate with slight phonon contributions, since it exhibits a tiny orthorhombic-to-monoclinic structural distortion at 328 K without any
Large enhancement of the thermopower in NaxCoO2 at high Na doping
TLDR
The conducting layered cobaltate NaxCoO2 exhibits several interesting electronic phases as the Na content x is varied, including water-induced superconductivity4 and an insulating state that is destroyed by field5.

The electrical properties of single crystals of p-type Bi(2)Te(3) are shown to be tuned by annealing as-grown crystals in elemental Te vapor at temperatures in the range of 400-420 °C. While as-grown
Electron-Phonon Coupling Mode in Excitonic Insulator
Ta2NiSe5 is considered a promising excitonic insulator (EI) candidate with slight phonon contributions, since it exhibits a tiny orthorhombic-to-monoclinic structural distortion at 328 K without any
CsBi(4)Te(6): A high-performance thermoelectric material for low-temperature applications
TLDR
The material CsBi(4)Te(6) has been synthesized and its properties have been studied, and at cryogenic temperatures, the thermoelectric properties appear to match or exceed those of Bi(2-x)Sb(x)Te (3-y)Se(y) alloys.
Zero-gap semiconductor to excitonic insulator transition in Ta2NiSe5
TLDR
The dome-like behaviour around EG∼0 combined with the transport, thermodynamic and optical results are fully consistent with an excitonic insulator phase in Ta2NiSe5, and the entropy associated with the transition being consistent with a primarily electronic origin.
Examination of Nonlinear Conductivity on the Excitonic Insulator Candidate Ta2NiSe5
The excitonic insulator candidate Ta2NiSe5 has been examined by means of the response to a pulse electric field. We observed linear current–voltage relationship at 200 V/cm, indicating the robustne...
