Low Temperature Measurements of Resistivity in Low-Density Polythylene

Salt Lake Community College

Measurements of resistivity of low density polyethylene (LDPE) have been made using the standard constant voltage method to determine the temperature dependence of resistivity. Where electrons are assumed to serve as the primary charge carriers, their mobility is believed to be dependent on their probability of hopping between trapping sites treated as potential wells. We consider our measurements of this relatively simple polymeric material using temperaturedependant models of conduction mechanisms developed for amorphous solids and semiconductors.
