We perform direct thermovoltage measurements in a single-electron transistor, using on-chip local thermometers, both in the linear and non-linear regimes. Using a model which accounts for co-tunneling, we find excellent agreement with the experimental data with no free parameters even when the temperature difference is larger than the average temperature (far-from-linear regime). This allows us to confirm the sensitivity of the thermovoltage on co-tunneling and to find that in the non-linear… Expand

Nonlinear Thermoelectricity with Electron-Hole Symmetric Systems.
This work demonstrates that a thermally biased junction can display an absolute negative conductance, and hence thermoelectric power, at a small but finite voltage bias, provided that the density of states of one of the electrodes is gapped and the other is monotonically decreasing. Expand

Cotunneling thermopower of single electron transistors
We study the thermopower of a quantum dot weakly coupled to two reservoirs by tunnel junctions. At low temperatures the transport through the dot is suppressed by charging effects (Coulomb blockade).Expand

Coulomb blockade oscillations in the thermopower of open quantum dots.
It is shown that Coulomb blockade oscillations of thermoelectric coefficients of a single electron transistor based on a quantum dot strongly coupled to one of the leads depends on temperature only logarithmically. Expand
Violation of the Wiedemann-Franz law in a single-electron transistor.
It is found that Coulomb interaction leads to a strong violation of the Wiedemann-Franz law: the Lorenz ratio becomes gate-voltage dependent for sequential tunneling, and is increased by a factor 9/5 in the cotunneling regime. Expand
Theory of the thermopower of a quantum dot.
A linear-response theory is presented for the thermopower of a quantum dot of small capacitance, and the periodicity of the oscillations is the same as that of the previously studied Coulomb-blockade oscillations in the conductance. Expand

Quantum thermal conductance of electrons in a one-dimensional wire.
An electron thermometer is used to measure the temperature rise of approximately 2 x 10(5) electrons in a two-dimensional box, due to heat flow into the box through a ballistic one-dimensional (1D) constriction, which deduces the thermal conductance kappa(Vg) of the 1D constriction. Expand
