In this research, a reliable negative differential mobility model was retrieved based on the experimental data using an iteration method. The experimental charge packet profiles were obtained by the polarization of the electron beam irradiated LDPE films (applied electric field intensity ranges from 30 kV/mm to 50 kV/mm). At the beginning of the research, a preliminary description of mobility-electric...
Numerous numerical simulations and analysis were performed to understand the phenomenon of space charge packets. In theory, the simulation of charge packet transport is based on the three physics principles: transport equation, continuity equation and Poisson's equation. As a key equation to simulate charge packet problem, it's very important to select an appropriate numerical algorithm to solve transport...
Electroluminescence generated during the short circuit of the polarized Linear low density polyethylene (LLDPE) sample is investigated. By measuring the electroluminescence and damped oscillation discharge current, the relations between the electroluminescence and discharge current was discussed. Results show that the luminescence comes from space charge recombination, which was partly demonstrated...
The electroluminescence during space charge recombination was investigated in this paper. The luminescent intensity was measured simultaneously at the moment that the polarized linear low density polyethylene (LLDPE) samples were short-circuited. The sample was polarized for about half an hour, then the polarizing field intensity was reduced to a certain value, which was called the discharge field...
