Abstract

A critical behavior associated with the delocalization of the charge-carrier wave function was manifested in our study of the spin/charge dynamics for a series of I₂-doped poly[2-buthoxy-5-methoxy-1,4-phenylenevinylene] conducting polymers employing conductivity and nuclear-magnetic-resonance measurements. Our results represent a demonstration of a critical behavior near a percolation threshold in a disordered system.
