The line shape of the thermopower oscillations depends strongly on the contributing tunneling processes. Between 1.5K and 40mK a crossover from a pure sawtooth to an intermittent sawtoothlike line shape is observed. The latter is attributed to the increasing dominance of cotunneling processes in the Coulomb blockade regime at low temperatures.
