Bipolar Hydrodynamical Model for Charge Transport in Graphene Nanoribbons
Journal of Computational and Theoretical Transport, 2022A hydrodynamical model for charge transport in narrow strips of graphene is here presented. The model takes into account the interactions with the well-known lattice vibrations and with the edge of the strip. The remarkable result is the modulation of the charge current due to the swapping of charge carriers between the conduction and the valence bands,

Extruded HVDC cable systems contain a multitude of different interface types. Physical interfaces are introduced on-site when the outer semi-conductive layer is removed prior to installing a pre-molded joint or stress-cone onto the cable end. Such interfaces are characterized by surface roughness, which can locally enhance electric field and stimulate ...

A model for bipolar charge transport in insulators
Proceedings of 1995 IEEE 5th International Conference on Conduction and Breakdown in Solid Dielectrics, 2002Failure of electrical cable insulation is still a major problem for the electricity generation and supply industries. Under high field conditions (>10/sup 8/ Vm/sup -1/), space charge and the concomitant electric field dynamics are involved in the initiation of dielectric breakdown.

Modeling effect of ferroelectric nanofiller size on bipolar charge transport in nanocomposite film
Journal of Polymer Science Part B: Polymer Physics, 2015Bipolar charge injection and field-dependent mobility transport through nanocomposite film comprised of ferroelectric ceramic nanofillers in an amorphous polymer matrix is simulated using a 3D particle-in-cell model which extends the classical electrical double layer by substitution of a dipolar core for the nanofiller.

A simple hole scattering length model for the solution of charge transport in bipolar transistors
IEEE Transactions on Electron Devices, 1999Considering the small warping parabolic heavy hole model with the quasi-elastic approximation in acoustic phonon scattering, it is shown that the hole scattering length is independent of the hole energy. This result now makes it possible to solve the Boltzmann transport equation to obtain a simple analytical solution for the ballistic hole transport in

Abstract For space charge simulation inside the insulating materials as to characterize the dielectric performance, apart from accuracy of the equivalent physical and mathematical models themselves, corresponding algorithms to be adopted are also crucial for a reliable solution.

We present a conduction model aimed at describing bipolar transport and space charge phenomena in low density polyethylene under dc stress. In the first part we recall the basic requirements for the description of charge transport and charge storage in disordered media with emphasis on the case of polyethylene.
