Abstract

This work presents an innovative approach to modeling the charge transport in dielectric polymers and their nanocomposites by coupling finite element analysis (FEA) with the Monte Carlo (MC) simulation. The stochastic charge hopping among localized states can be well captured by the MC simulation. The altered electric field distribution due to nanofillers can be computed by FEA and contributes to the energy landscape of the localized states. The modeling faithfully reproduces the transient and dispersive nature of the transport as exhibited in many experiment measurements. With nanofillers as deep traps, the modeling also demonstrates the importance of the filler morphology to the effectiveness of charge trapping.
