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

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.

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.

In this paper, finite element method correlated with boundary conditions has been used to solve the Poisson’s equation. Splitting method, solving the continuity equation in two-time step, with and without term source associated with new Schottky injection application, however, Runge–Kutta method with a Gaussian filter calculated the distribution of all

Numerical modelling for bipolar charge transport in polyethylene under high DC applied voltage
2014 International Conference on Electrical Sciences and Technologies in Maghreb (CISTEM), 2014In this paper, a bipolar transport model for low-density polyethylene under DC voltage, theorecale formulation of the model is based on the poisson's equation and continuity, transport equation. As well as on the appropriate models for injection and take into account trapping and detrapping and recombination mechanism.

Experimental studies of charge injection and transport of holes and electrons in LUMATION™ Green 1300 Series light-emitting polymer (LEP) by a combination of experimental techniques are reported. It is found that hole mobility is lower than electron mobility and the former exhibits steeper electric-field dependence thus reducing the misbalance between ...

HVDC extruded cable is the key equipment of flexible DC transmission technology. However, the interface charge between different dielectrics is easy to accumulate in the HVDC cable accessories due to the discontinuity of conductivity and permittivity, which will threaten the safety of the HVDC cable system. The injection and transportation behaviors of

We present a bipolar model of conduction providing time-dependent solutions for charge densities under uniform DC field. The model assumes the existence of an exponential distribution of trap depth for electrons and holes, with an upper limit in trap depth. Charges are supplied through Schottky injection at both electrodes.
