Abstract
The results are presented of calculations, for a model three dimensional system, of the effect of the introduction of various types and amounts of disorder into a crystal on the shape of the electronic density of states curve. It is found that even a small amount of disorder is sufficient to remove the van Hove singularities in the centre of the band, while in general the amount of distortion introduced depends on the amount of irregularity in the density of states curve for the perfect crystal, the amount of disorder, and whether this disorder resembles that appropriate to an amorphous system or that appropriate to an alloy.Keywords
