NettetThe Poisson-Boltzmann equation is a non-linear partial differential equation. It can be simplified un-der the assumption that eψ/kT is very small and so e−eψ/kT is approximately equal to 1 − eψ/kT. This is sometimes called the Debye-Huc¨ kel approx-imation and the resulting Poisson-Boltzmann equa-tion is called the linear Poisson ...
