Abstract
We demonstrate the stepwise fabrication of parallel double quantum dots in GaAs/AlGaAs-heterostructures. The atomic force microscope serves as a direct lithographic tool for the processing of our samples. The devices are characterized by transport measurements. Coulomb-blockade oscillations and diamonds with different periods for the two quantum dots are observed.
