None:
A software packet for simulating charge carrier transport in solid electrolytes on the basis of Nernst-Planck Poisson equations is presented. The software is capable of handling a variety of electrochemical ion exchange processes ranging from charge attachment induced transport (CAIT) to alkali proton substitution (APS) and thermal electro-poling with a focus on concentration depth profiles. The software package includes a graphical user interface allowing for simple user input, visualization and output.

Carrier Transport
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:
Electron Carriers
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...
Carrier Generation and Recombination
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
Indirect generation involves an...

Charging Conductors By Induction
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...
