Bipolar charge injection and transport has been observed in corona charged low density polyethylene (LDPE) during surface potential decay (SPD) processes. The proposed bipolar charge transport (BCT) model can well interpret the SPD characteristics, especially the SPD crossover phenomenon. Bipolar charge transport in materials can result in charge recombination (CR). It is evident that CR can affect...
Bipolar charge transport (BCT) model has been widely used to simulate time/space evolution of space charges in insulating materials. The BCT simulations are performed to investigate the relationships between space charge accumulation and conduction, electroluminescence (EL), charge packet formation, electrical breakdown, and surface potential decay (SPD) properties. Accordingly, the charge advection-reaction...
To evaluate spacecraft charging level and predict surface and internal electrostatic discharging (ESD) probability, it is important to know the charge transport properties of high insulation materials, such as epoxy resin/glass composition (FR4), Teflon and polyimide. In present work, the charge transport properties of the space insulators are revealed by a bipolar charge transport (BCT) model combined...
