CHARACTERIZATION OF THE DELOCALIZED STATES IN A CONTINUOUS CORRELATEDDISORDER MODEL

We study the delocalisation of electronic states in a correlated disor der potential in the form of the Kronig-Penny model. Our results are c ompatible with the other works claiming a band of Bloch-like extended states for large system sizes. We have made a clear physical distincti on between the extended states forming the band and the resonant struc tures observed in the transmittance peaks away from the band by doing Argand map study for the phase of the wavefunction and its multifracta l scaling analysis. We believe this work resolves the recent controver sies regarding the nature of transmitting states in the correlated dis order models.
