摘要
Modulation doped GaAs/AlGaAs heterostructures have been grown by molecular beam epitaxy with a layer of self-assembled InGaAs quantum dots located in the center of the undoped AlGaAs spacer. Electron beam lithography and etching techniques were used to define 70 mn wide current channels in combination with lateral side gates. Depending on the direction of gate voltage sweeps the onset of conductance differs by up to 1.7 V, which is associated to charging and discharging of the quantum dots in the spacer. From Coulomb blockade oscillation single electron effects are revealed.
