Thermopower and thermal conductivity of superconducting perovskite $MgCNi_3$ [PDF]
Phys. Rev. B 65, 064534 (2002), 2001 The thermopower and thermal conductivity of superconducting perovskite $MgCNi_3$ ($T_c \approx$ 8 K) have been studied. The thermopower is negative from room temperature to 10 K. Combining with the negative Hall coefficient reported previously, the negative thermopower definetly indicates that the carrier in $MgCNi_3$ is electron-type.

Effect of assisted hopping on thermopower in an interacting quantum dot
New Journal of Physics, 2014 We investigate the electrical conductance and thermopower of a quantum dot tunnel coupled to external leads described by an extension of the Anderson impurity model which takes into account the assisted hopping processes, i.e., the occupancy-dependence ...

Orbital caloritronic transport in strongly interacting quantum dots
New Journal of Physics, 2014 We discuss population imbalances between different orbital states due to applied thermal gradients. This purely thermoelectric effect appears quite generically in nanostructures with a pseudospin (orbital) degree of freedom.

Time-Dependent Thermopower Effect in an Interacting Quantum Dot [PDF]
Int J Thermophys. (2012), 2012 The time-dependent thermopower is analyzed through an interacting quantum dot coupled to a time-dependent gate voltage and under the influence of an external magnetic field using the Keldysh nonequilibrium Green's function formalism. Formal expressions of the electrical and thermal conductances, thermopower, and thermoelectrical figure of merit are ...

Coulomb Blockade Oscillations in the Thermopower of Open Quantum Dots [PDF]
, 2000 We consider Coulomb blockade oscillations of thermoelectric coefficients of a single electron transistor based on a quantum dot strongly coupled to one of the leads. Analytic expression for the thermopower as a function of temperature $T$ and the reflection amplitude $r$ in the quantum point contact is obtained.
