Abstract

The objective of the paper is to present a consistent explanation of the Meyer-Neldel rule (MNR) together with the “further MNR”. The explanation, is based on the barrier-cluster model and the assumption that recombination are accompanied with emitting a series of phonons (each with the energy ∆E). The total probability of the multi-phonon emission decreases with the growth of the number of the phonons. The “further MNR” takes into account the fact that the phonons produced during the recombination process are intensively absorbed by free electrons in sub-band of low average mobility..
