Abstract

Polyimide (Kapton) foils can be transformed from insulating to conducting materials by irradiating them with excimer laser pulses. Photothermal measurements show that the disordered materials exhibit low thermal diffusivity across the material due to phonons and variable range hopping of electrons along the localized conducting traces above and below the percolation threshold, respectively.
