✦ Synopsis

We observe Aharonov-Bohm oscillations in an interferometer containing one quantum dot in each arm. The two quantum dots are laterally deÿned in a two-dimensional electron gas and are both brought to the few electron limit. By the results we verify that at least part of the charge transport is coherent in such a mesosopic system.

The time-dependent electron transport through an Aharonov-Bohm ring embedded with two quantum dots in the presence of external microwave (MW) fields are investigated theoretically by using the nonequilibrium Green's function method. Whether the MW field can induce or suppress the Fano resonance depe
