We use both Quantum Hall and Shubnikov de Haas experiments at high magnetic field and low temperature to analyse broadening processes of Landau levels in a δ-doped 2D quantum well superlattice and a 1D quantum wire superlattice generated from the first one by controlled dislocation slips. We deduce

The minibands of p-type δ-doping superlattices (SLs) in GaAs are studied in dependence on acceptor sheet doping concentrations N A and SL periods d. The calculations rely on effective mass theory, applied to the 8 valence band hole gas. Hole-hole interaction is selfconsistently taken into account, i

The quantum mobility has been measured in δ-doped GaAs/Al x Ga 1-x As/GaAs structures in which one is able to vary the population of DX states. The experiments show that spatial correlations in the charge distribution enhance the quantum mobility. We are able to correctly account for these correlati
