When the gate voltage defining the dot is swept, the thermovoltage across the dot oscillates about zero with a period equal to that of the CB oscillations in electrical conductance and with a magnitude consistent with a Landauer formulation. In addition, a reproducible fine structure on top of the CB oscillations in the thermovoltage was observed that appears to result from the N-particle excitation spectrum of the dot. © 1997 The American Physical Society. |
