Capacitance-voltage profiling measurements have been performed to characterize the properties of centre delta-doped Al0.27Ga0.73As/GaAs quantum wells. The subband energies, energy wavefunctions and subband carrier densities were determined using the experimental results and a self-consistent calculation taking into account the exchange correlation effects.
