Influence of Metallization on the Barrier Height of Injection of Low Density Polyethylene Using Optimization Algorithm

This article discusses an optimization method which is substantially based on the Trust-Region algorithm. At the same time, it attempts to configure the physical parameters pertaining to charge transport model for dielectrics. It is worth mentioning that the experimental data used are inherent to net density charge where the data are measured by Pulse Electro Acoustic method (PEA) in company with what is known by external charging current measurements. The simulated data are obtained by a bipolar charge transport model which is developed for Low Density Polyethylene (LDPE). This paper proposes a protocol that can contribute in figuring out a unique set of parameters for the model. Moreover, the effects of electrode materials on space charge formation in Low-Density Polyethylene have been investigated and discussed.
