Abstract

In this paper, the electrical conduction phenomena of oriented polypropylene film were studied. Especially, as for the range of negative characteristics, it is observed that as increasing ambient temperature, the characteristics are shifted gradually towards the low intensity side of applied field with the decreasing width of the range as well as the fact that the currant oscillation takes place at the both transition points of the characteristics and that the point at the place the dielectric breakdown, occurs. Finally, it is also suggestive that the oscillation characteristics observed on the negative resistance range of the biaxially oriented specimen show the possibility to utilize it as active element materials.
