## Drift And Diffusion Current Pdf

This current is calculated numerically for iso‐tropic point defects in an anisotropio elastic continuum. The diffusion current is found to be a fixed fraction of that caused by a spherical potential for which the current can bewritten by a simple analytical expression.

- 3. 1. 2 Drift-Diffusion Current Equations The popular drift-diffusion model can be derived directly from Boltzmann's transport equation by the method of moments or from the basic principles of irreversible thermodynamics . In this model the electron current density is expressed as a sum of two components: The drift component which is driven by
- Overview. Drift current is the electric current caused by particles getting pulled by an electric field. The term is most commonly used in the context of electrons and holes in semiconductors, although the same concept also applies to metals, electrolytes, and so on.
