abstract = {We report on the first measurement of the Seebeck
coefficient in a tunnel-contacted and gate-tunable
individual single-quantum dot junction in the Kondo regime,
fabricated using the electromigration technique. This
fundamental thermoelectric parameter is obtained by directly
monitoring the magnitude of the voltage induced in response
to a temperature difference across the junction, while
keeping a zero net tunneling current through the device. In
contrast to bulk materials and single molecules probed in a
scanning tunneling microscopy (STM) configuration,
investigating the thermopower in nanoscale electronic
transistors benefits from the electric tunability to
showcase prominent quantum effects. Here, striking sign
changes of the Seebeck coefficient are induced by varying
the temperature, depending on the spin configuration in the
quantum dot. The comparison with numerical renormalization
group (NRG) calculations demonstrates that the tunneling
density of states is generically asymmetric around the Fermi
level in the leads, both in the cotunneling and Kondo
regimes.},
