Thermoelectric Power and Hall Effect in Correlated Metals and Doped Mott-Hubbard Insulators: DMFT approximation [PDF]

JETP 137, No. 6, 927-939 (2023), 2023
We present comparative theoretical investigation of thermoelectric power and Hall effect in the Hubbard model for correlated metal and Mott insulator (considered as prototype cuprate superconductor) for different concentrations of current carriers. Analysis is performed within standard DMFT approximation. For Mott insulator we consider the typical case

Nickel-Fullerene Nanocomposites as Thermoelectric Materials

Nanomaterials, 2022
Nickel films with nanovoids filled with fullerene molecules have been fabricated. The thermoelectric properties of the nanocomposites have been measured from room temperature down to about 30 K. The main idea is that the phonon scattering can be enhanced

Large Spin-Dependent Thermoelectric Effects in NiFe-based Interconnected Nanowire Networks

Nanoscale Research Letters, 2020
NiFe alloy and NiFe/Cu multilayered nanowire (NW) networks were grown using a template-assisted electrochemical synthesis method. The NiFe alloy NW networks exhibit large thermopower, which is largely preserved in the current perpendicular-to-plane ...
