Abstract :
The authors show that in the case of Kapton(R) HN films, ion hopping through the potential barriers with different heights (characterised by a distribution function) is the most probable mechanism of DC conductivity. Even small differences in barrier heights W strongly influence the vn product. Increase of the hopping probability results as well from the decrease of the barrier height by the applied electric field. This causes temperature dependence of the hopping distance
