Charge fluctuations in hydrogenated amorphous silicon
TL;DR: In this article, the electronic density of states and the charge distribution using a Weaire-Thorpe tight binding hamiltonian, which was generalized to include Hydrogen atoms, were calculated using the recursion method.

Electrons in disordered systems with strong short-range order and off-diagonal randomness
TL;DR: In this paper, a cluster theory, which contains off-diagonal randomness, configurational short-range order and diagonal randomness is applied to the study of electrons in damaged honeycomb lattices with correlated unpaired bonds.

Density of states and charge distribution in hydrogenated amorphous silicon
TL;DR: In this article, the local density of states and the charge distribution in a cluster model of hydrogenated amorphous silicon was calculated using the recursion method, which indicated an average charge transfer of 0.3 electrons from silicon to hydrogen.

Phonons in disordered systems with strong short-range order. III. ODR in honeycomb lattices
TL;DR: In this article, a cluster theory with configurational short-range order and diagonal randomness is applied to the study of transverse phonons in damaged honeycomb lattices with correlated unpaired bonds, e.g. microscopic cracks, dangling bonds, vacancies and voids.

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.
