Effect of the Order-Disorder Transition on the Seebeck Coefficient of Nanostructured Thermoelectric Cu₂ZnSnS₄

Nanomaterials, 2019
Bulk samples of kesterite (Cu2ZnSnS4, CZTS) were produced by cold-pressing and sintering of CZTS powders obtained via reactive ball-milling. An increase in the Seebeck coefficient of more than 100 μV/K, almost doubling the expected value, is noticed

Large morphological sensitivity of the magneto-thermopower in Co/Cu multilayered systems

New Journal of Physics, 2015
We present results of first-principles calculations on the transport properties, both under an electric field or a temperature gradient, in Co/Cu multilayered systems. The various effects brought about by the changes in the morphological parameters, such

Magnetic Contribution to the Seebeck Effect

Entropy, 2018
The Seebeck effect is derived within the thermodynamics of irreversible processes when the generalized forces contain the magnetic term M ∇ B . This term appears in the formalism when the magnetic field is treated as a state variable.

Thermoelectric energy conversion: Assessment of limiting capabilities

Physics of Complex Systems
Based on a thermodynamic ratio between the thermopower coefficient and entropy of the electrically conducting medium, we obtained an estimated value of the thermoelectric efficiency parameter ZT for an electronic system of fully ionised plasma.
