Abstract

The conductivity in a phase-separated conductor-insulator composite fiber is found to be quite different from that of a percolating system. There is evidence that the placement of the conducting domains is in an ordered, rather than in a random, manner within the insulating matrix, with the conductivity being limited by tunneling from one conducting domain to another. The conductivity is found to scale as exp(αφ{symbol}^{1 3}) over a wide range of conductor volume fractions φ{symbol}.
