Semiconductor quantum dots have been patterned into a Ga [Al]As heterostructure by local oxidation of the GaAs cap layer with an Atomic Force Microscope. The combination of high electron density and reduced shape deformation allows us to observe spin pairs in the dot's energy level spectrum, which i
