Diffusion of Electrons in Quasi-1D Polymer Structures with Random Interchain Couplings
PHY S I CAL REV I EW LETTERS 18 NOVEMBER 1996 VOLUME 77, NUMBER 21，-0001，（）：
We study electronic diffusion in quasi-one-dimensional systems with randomly placed interchain single and double bond cross-links corresponding to one and two adjacent interchain hoppings, respectively. While in the single bond case all states are localized, for the double bond case many completely unscattered states are obtained forming a "dilute" conducting band which leads to superdiffusive wave packet dynamics. This new type of band structure can explain the unusual transport properties of highly conducting polymers.
