TLDR
In this article, a generalised coherent potential approximation is used to describe a chemically disordered material and the method gives not only the density of states for such a system but also reliable values of the total energy.Abstract:
A generalised coherent potential approximation is used to describe a chemically disordered material. It is shown that the method gives not only the density of states for such a system but also reliable values of the total electronic energy. The model is applied to a binary metal alloy where it is seen that a pseudo gap develops prior to the development of an ordered phase and in both cases the conductivity is anticipated to be lowered.read more

Theory of Short-Range Order and Disorder in Tetrahedrally Bonded Semiconductors
TL;DR: In this paper, the authors present a review of short-range order and disorder in tetrahedrally bonded semiconductors and the relationships between the two, and discuss the roles of shortrange order (SRO), long-range ordering (LRO), shortrange disorder (SRD), and long range disorder (LRD).

TL;DR: In this paper, a method for studying the electronic structure of binary alloys within the tight-binding framework is presented and developed in detail, which involves treating part of the system exactly as a cluster of atoms and simulating the rest of the environment by connecting to each atom at the surface of the cluster a Bethe lattice of the same coordination number.
