Enhanced Thermoelectric Power and Electronic Correlations in RuSe$_2$

, 2015
We report the electronic structure, electric and thermal transport properties of Ru$_{1-x}$Ir$_{x}$Se$_2$ ($x \leq 0.2$). RuSe$_2$ is a semiconductor that crystallizes in a cubic pyrite unit cell. The Seebeck coefficient of RuSe$_2$ exceeds -200 $\mu$V/K

Giant nonlinear conduction and thyristor-like negative derivative resistance in BaIrO3 single crystals

, 2005
We synthesized single-crystalline samples of monoclinic BaIrO3 using a molten flux method, and measured their magnetization, resistivity, Seebeck coefficient and nonlinear voltage-current characteristics.

Effective modelling of the Seebeck coefficient of Fe₂VAl [PDF]

Journal of Physics: Condensed Matter, 2019
Previous first-principles calculations have failed to reproduce many of the key thermoelectric features of Fe2VAl, e.g. the maximum values of the Seebeck coefficient S and its asymmetry with respect to the chemical potential. Also, previous theoretical predictions suggested that the pseudo band gap of Fe2VAl switches from indirect to direct upon doping.

Unconventional density wave in CeCoIn_5?

, 2004
Very recently large Nernst effect and Seebeck effect were observed above the superconducting transition temperature 2.3K in a heavy fermion superconductor CeCoIn_5. We shall interpret this large Nernst effect in terms of unconventional density wave (UDW),

Longitudinal Seebeck coefficient of the charge ordered layered crystals in a strong quantizing magnetic field [PDF]

arXiv, 2013
The longitudinal Seebeck coefficient of the charge-ordered layered crystals in a strong quantizing magnetic field normal to layers plane has been determined. The conditions whereby charge ordering parameter and chemical potential are oscillating functions of magnetic field induction are considered.

"Pudding Mold"-type Band as an Origin of Large Thermopower in tau-type Organic Conductors

, 2010
We study the origin of the large thermopower in quasi-two-dimensional a $\tau$-type organic conductor, $\tau-(EDO-S,S-DMEDT-TTF)_2(AuBr_2)_{1+y}$ ($y \le 0.875$), from the view point of a "pudding mold"-type band structure.

First-Principles Thermodynamic Theory of Seebeck Coefficients

Physical Review B, 2018
Thermoelectric effects, measured by the Seebeck coefficients, refer to the phenomena in which a temperature difference or gradient imposed across a thermoelectric material induces an electrical potential difference or gradient, and vice versa, enabling the direct conversion of thermal and electric energies.
