Semiconductors are much more changed by disorder than metals or insulators, and appear to be the most suitable materials for fundamental work. Considerable exploratory work on am

The Nature of the Amorphous State,materials and their transformations are reviewed. Also, structural and chemical changes which can lead to inhomogeneities, and the detection of these inhomogeneities, are discussed. Because of the difficulty in completely characterizing amorphous materials, one must be aware of the possible structur

Indeed, this is one of the few properties of crystals which cannot be accounted for on the basis of short-range order alone: If the long-range order is destroyed, the sharp structural detail, which is typical for crystals, disapp
