Abstract
The widespread observation of the Meyer–Neldel rule has been explained as associated with large activation energies, requiring the accumulation or annihilation of a large number of excitations for a kinetic event to take place. The characteristic Meyer-Neldel or isokinetic temperature is then proportional to the energy of these excitations divided by a coupling constant. For disordered materials at low excitation energies, a similar relation has been proposed, involving the width of bandtails or of Gaussian distributions, a measure of disorder. This similarity has resulted in interpreting high activation energy results, for which it cannot be applicable, using this description. We show that this leads to contradictions with experiments as well as to logical contradictions.
