Journal of Physics D: Applied Physics, 2022 Abstract Predicting the electric field distribution in polymers used as electrical insulating materials remains the Holy Grail, as the presence of charges disturbs the Laplacian electric field. Charges arising from the electrodes are one of the dominant mechanisms of charge generation, particularly in polyethylene-based materials. Hence,

Bipolar charge transport model to estimate charging and degradation processes in electron-beam-irradiated LDPE films [PDF]
Journal of Physics D: Applied Physics, 2019 Abstract Improvement of the performances of dielectric materials subjected to electrical stresses is one of the challenging objectives in a large number of domains of industrial applications. Achieving this goal requires a better understanding of the physical processes governing the behavior of dielectrics and their long-term ...

Modeling of Charge Transport in Ion Bipolar Junction Transistors
Langmuir, 2014 Spatiotemporal control of the complex chemical microenvironment is of great importance to many fields within life science. One way to facilitate such control is to construct delivery circuits, comprising arrays of dispensing outlets, for ions and charged biomolecules based on ionic transistors.
