Abstract

The connection between the Meyer-Neldel rule (MNR) and Urbach rule (UR) is briefly discussed in this paper from the viewpoint of the barrier-cluster model of disordered semiconductors. We assume that a significant role in this connection has to be ascribed to monoenergetical phonons produced in the process of non-radiative recombination of the electronholes (e-h) pairs..
