The influence of frequency of AC component on space charge behaviours in polyethylene under combined AC and DC electric fields [PDF]
, 2014 Combined ac and dc voltages may occur in high voltage power transmission system, which bring challenges to the dielectric materials. Generally speaking, space charge is well recognised under high voltage dc conditions but has received little attention ...

In-depth understanding of boosting salinity gradient power generation by ionic diode
iScience, 2023 Summary: Ionic diodes constructed with asymmetric channel geometry and/or charge layout have shown outstanding performance in ion transport manipulation and reverse electrodialysis (RED) energy collection, but the working mechanism is still indistinct ...

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.

Simulation of Bipolar Charge Transport in Graphene by Using a Discontinuous Galerkin Method [PDF]
Communications in Computational Physics, 2019 Summary: Charge transport in suspended monolayer graphene is simulated by a numerical deterministic approach, based on a discontinuous Galerkin (DG) method, for solving the semiclassical Boltzmann equation for electrons. Both the conduction and valence bands are included and the interband scatterings are taken into account.

Transport phenomena in bipolar semiconductors: a new point of view [PDF]
, 2005 In previous work it has been shown that the traditional approach to transport phenomena in bipolar semiconductors is inconsistent. In particular, the effect of non-equilibrium charge carriers and appropriate boundary conditions are not considered in the ...

Space Charge Accumulation and Decay in Dielectric Materials with Dual Discrete Traps
Applied Sciences, 2019 Charge trapping and de-trapping properties can affect space charge accumulation and electric field distortion behavior in polymers. Dielectric materials may contain different types of traps with different energy distributions, and it is of interest to ...
