摘要：
The transport properties of a quantum wire (QW) with a quantum dot (QD) coupled to one side has been studied. The structure is formed by metallic gates on a GaAs/AlGaAs heterostructure. The conductance of the QW oscillates periodically as the number of electrons in the QD is increased due to the tunnel coupling between the QW and the QD. We measured these oscillations in detail by changing the coupling strength, the wire width, and magnetic fields. The measurements indicate that the side-coupled QD scatters the conduction electrons in the QW.
