We present an experimental study of the uctuations of Coulomb blockade peak positions of a quantum dot. The dot is deÿned by patterning the two-dimensional electron gas of a silicon MOSFET structure using stacked gates. The ratio of charging energy to single-particle energy is considerably larger th
