摘要：

We present measurements of the conductance of a quantum dot in the presence of 2, 1, and 0 adiabatically transmitted edge channels. In all three cases periodic conductance oscillations are observed as a function of gate voltage. By using the oscillations observed in the absence of edge channels as an electron counter we demonstrate that the oscillations observed in the presence of edge channels are due to the influence of Coulomb charging. Using the temperature dependence of the conductance oscillations we have then estimated the activated Coulomb charging energy.
