Samenvatting

The structural properties of a square periodic array of quantum dots of a GaAs/AlAs superlattice were studied by x-ray diffractometry. If the azimuthal direction of the primary beam can be expressed by integer Miller indices, the profile is perfectly periodic. However, if its azimuthal orientation is determined by tg() ˜ 0.618 (the golden mean value), the diffraction maxima exhibit Fibonacci sequences in reciprocal space, i.e. a quasi-periodic diffraction curve.
