Positive Seebeck Coefficient in Highly Doped La2−xSrxCuO4 (x = 0.33); Its Origin and Implication

Simultaneous increase in electrical conductivity and Seebeck coefficient in highly boron-doped nanocrystalline Si.

A large thermoelectric power factor in heavily boron-doped p-type nanograined Si with grain sizes ∼30 nm and grain boundary regions of ∼2 nm is reported. The reported power factor is ∼5 times higher than in bulk Si. It originates from the surprising observation that for a specific range of carrier concentrations, the electrical conductivity and Seebeck coefficient increase simultaneously. The t...

Pressure Effect of Seebeck Coefficient for Zinc Doped Tin Clathrates

We measured the temperature dependence of electrical resistance (R) and thermopower (S) of Cs8Zn4Sn42 under high pressure up to 1.2 GPa. Both R and |S| at room temperature increased with pressure. We observed gap widening, irreversible |S| increasing under high pressure, which were similar to the behaviors of Cs8Sn44. However, the relaxation effect of R for Cs8Zn4Sn42 was negligible in contrast...

First principles explanation of the positive Seebeck coefficient of lithium.

Lithium is one of the simplest metals, with negative charge carriers and a close reproduction of free-electron dispersion. Experimentally, however, Li is one of a handful of elemental solids (along with Cu, Ag, and Au) where the sign of the Seebeck coefficient (S) is opposite to that of the carrier. This counterintuitive behavior still lacks a satisfactory interpretation. We calculate S fully f...

Computational Seebeck Coefficient Measurement Simulations

We have employed finite element analysis to develop computational Seebeck coefficient metrology simulations. This approach enables a unique exploration of multiple probe arrangements and measurement techniques within the same temporal domain. To demonstrate the usefulness of this approach, we have performed these Seebeck coefficient measurement simulations to quantitatively explore perturbation...
