Abstract

At relatively high temperatures the electron transport in single electron transistors in the Coulomb blockade regime is dominated by the processes of sequential tunneling. However, as the temperature is lowered the cotunneling of electrons becomes the most important mechanism of transport. This does not affect significantly the general behavior of the conductance as a function of the gate voltage, which always shows a periodic sequence of sharp peaks. However, the shape of the Coulomb blockade oscillations of the thermopower changes qualitatively. Although the thermopower at any fixed gate voltage vanishes in the limit of zero temperature, the amplitude of the oscillations remains of the order of 1/e.
