Laser Programmed Conducting Polymers.

Abstract

The metal insulator transition observed in excimer laser irradiated polyimide was characterized in terms of percolation theory. The critical exponent for electrical conductivity was measured to be 2.00 = or - 0.05 in exact agreement with the percolation theory predictions. Carbon fiber formation under an applied electric filed was also observed and investigated. The observation of nonlinear I-V characteristics and the relation of this observation to the percolation theory is an object of continuing investigations. (MM)
