Abstract
The authors calculate the AC and DC current through a quantum double-barrier heterostructure taking into account Coulomb interactions in the well. The AC conductance has a periodic dependence on the external field frequency corresponding to the single-electron-level spacing, and as a function of the leads' chemical potential with a period determined by the interaction. These two different periods enable probing of the two characteristic energy scales of the quantum-dot structure.
