Lw. Molenkamp et al., SAWTOOTH-LIKE THERMOPOWER OSCILLATIONS OF A QUANTUM-DOT IN THE COULOMB-BLOCKADE REGIME, Semiconductor science and technology, 9(5), 1994, pp. 903-906
Current heating is used to measure the thermopower of a quantum dot in
the Coulomb blockade regime. We observe sawtooth-like oscillations as
a function of gate voltage in the thermovoltage across the dot. These
observations are compared with measured Coulomb blockade oscillations
in the conductance, and with theory.
