The theory and properties of randomly disordered crystals and related physical systems
TL;DR: A review of the methods for determining the behavior of solids whose properties vary randomly at the microscopic level, with principal attention to systems having composition variation on a well-defined structure (random "alloys") can be found in this paper.

Persistence and Amalgamation Types in the Electronic Structure of Mixed Crystals
Yositaka Onodera,Yutaka Toyozawa +1 more
TL;DR: In this article, the intrinsic optical spectra of binary solid solutions can be classified into two types, persistence and amalgamation types, and various situations realized in mixed crystals are discussed in the light of the experimental information.
Journal ArticleDOI
Contribution to the Theory of Disordered Alloys
TL;DR: In this paper, a simple model of a disordered substitutional alloy, similar in some respects to transition-metal alloys, is studied in several approximations, and the average density of states for several model alloys is investigated, and it is found that corrections to the rigidband model can be significant even in situations in which the constitutents are not very dissimilar.

Exciton Superexchange, Resonance Pairs, and Complete Exciton Band Structure of 1B2u Naphthalene
Hwei Kwan Hong,Raoul Kopelman +1 more
TL;DR: In this paper, a method for the determination of complete exciton band structures in molecular crystals is given, using an exciton "superexchange" approach, which is applicable to nontrivial interchange symmetry systems, within the restricted Frenkel-Davydov theory.

Electronic States of Heavily Doped Molecular Crystals—Naphthalene. I. Theoretical
Hwei‐Kwan Hong,G. Wilse Robinson +1 more
TL;DR: In this paper, the energy spectrum of heavily doped molecular crystals was treated in the Green's function formulation and the mixed-crystal green's function was obtained by averaging over all possible impurity distributions.
