Electrical Conduction in 3-Percent Carbon-Filied Polyethylene-Part 11: High-Field Results

The high-field conduction properties of 3% carbon-filled polyethylene were investigated. Detailed step-response measurements were made as a function of temperature and applied field. A near-quadratic dependence of the steadystate conduction current upon applied voltage was observed. The steady-state and transient absorption and resorption currents are discussed in the framework of physical models of space-charge limited conduction and charge carrier trapping.
