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)
