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.

Space charge behaviours in polyethylene under combined AC and DC electric fields
, 2014 Polyethylene has been one of the widely studied polymeric insulation materials. One of the major issues related to polymeric materials is the easy formation of space charge which may cause electric field enhancement. In this paper, a numerical simulation

Charge Transport: Paths and Energy Profiles [PDF]
, 2022 To maintain life, charge transfer processes must be efficient to allow electrons to migrate across distances as large as 30 – 50 Å within a timescale from picoseconds to milliseconds, and the free-energy cost should not exceed one electron volt.

A new model for surface potential decay of corona-charged polymers [PDF]
, 2010 Surface potential measurement provides a useful tool to gauge the electrical properties of materials. It has been observed that the potential of a sample with an initial high surface potential decays faster than that with an initial lower surface ...

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.
