Weak field magnetoresistance was explored in GaAs/AlGaAs superlattices with different strengths of disorder produced either by the random variation of the well thicknesses or by the interface roughness. Depending on the disorder strength, three different regimes of the quantum transport were distinguished: the regimes of weak localization identified as the regimes of propagative and diffusive Fermi surfaces and the strongly localized insulating regime. Our results imply different dephasing mechanisms in the weak and strong localization limits. The vertical coupling energies in the superlattices determined with the random variation of the well thicknesses revealed a significant decrease with increasing disorder strength.
