ActivationmeV

Description

The ActivationmeV fitting function can be written as:

\[y = A_R e^{-\frac{E\times b}{1000 k_B x}}\]

where: - A_R - Attempt Rate - b - Barrier energy - E - activation energy - k_B - Boltzmann Constant - x - is in meV

Alternatively use the ActivationK <func-ActivationK> fitting function when fitting to Kelvin.

Examples

An example of when this might be used is for examining the ion dynamics in flouride-containing polyatomic anion cathodes using muon spectroscopy [1].
