RT Journal Article T1 Experimental evidence of delocalized states in random dimer superlattices A1 Bellani, V. A1 Díez Alcántara, Eduardo A1 Hey, R. A1 Toni, L. A1 Tarricone, L. A1 Parravicini, G.B. A1 Domínguez-Adame Acosta, Francisco A1 Gómez-Alcalá, R. AB We study the electronic properties of GaAs-AlGaAs superlattices with intentional correlated disorder by means of photoluminescence and vertical de resistance. The results are compared to those obtained in ordered and uncorrelated disordered superlattices. We report the first experimental evidence that spatial correlations inhibit localization of states in disordered low-dimensional systems, as our previous theoretical calculations suggested, in contrast to the earlier belief that all eigenstates are localized.
