| Abstract: | We investigate the transport properties of a random binaryside-coupled chain by using the transfer-matrix technique. It isfound that there are resonant states in the systems with short-rangecorrelations between the host chain atoms and the side-coupledatoms. The analytic expressions for the extended states are alsopresented in the systems with the side couplings between like atomsand between unlike atoms. |
| Keywords: | localization in disorderedstructures extended states resonance |
