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.

Effect of solvation shell structure on thermopower of liquid redox pairs
EcoMat, 2023 Developing redox electrolytes with high thermopower is the key to making efficient thermogalvanic batteries for harvesting low‐grade heat. This work applies molecular dynamics simulations to predict the thermopower (i.e.

Study of the Thermoelectric Properties of Chrome Silicides
East European Journal of PhysicsThe temperature dependences of the thermoelectromotive force of chromium mono and disilicides in the temperature range 200℃÷+600℃ have been studied. For chromium disilicide, the dependence of the thermopower coefficient (α) on temperature (T) has three ...

Phase transition enhanced thermoelectric figure-of-merit in copper chalcogenides
APL Materials, 2013 While thermoelectric materials can be used for solid state cooling, waste heat recovery, and solar electricity generation, low values of the thermoelectric figure of merit, zT, have led to an efficiency too low for widespread use.

Thermopower Enhancement from Engineering the Na0.7CoO2 Interacting Fermiology via Fe Doping
Advances in Condensed Matter Physics, 2018 The sodium cobaltate system NaxCoO2 is a prominent representant of strongly correlated materials with promising thermoelectric response. In a combined theoretical and experimental study we show that, by doping the Co site of the compound at x=0.7 with ...
