%X We study how the in8uence of structural correlations in disordered systems manifests itself in experimentally measurable magnitudes, focusing on dc conductance of semiconductor superlattices with general potential pro6les. We show that the existence of bands of extended states in these structures gives rise to very noticeable peaks in the 6nite-temperature dc  conductance as the chem ical potential is moved through the bands or as the temperature is increased from zero. On the basis of these results we discuss how dc conductance measurements can provide information on the location and width of the bands of extended states. Our predictions can be used to demonstrate experimentally that structural correlations inhibit the localization eKects of disorder.
