Cluster Scattering in Amorphous Semiconductors and Liquid Metals
Although the study of the electronic structure and derived properties of condensed matter has been one area of great development in the past decade, attention has been focused mainly on the band structure of crystalline solids, their fermi surfaces, etc. In recent years some understanding of the electronic properties of random alloys in periodic or almost periodic lattices has been obtained through the use of the coherent potential, the virtual crystal approximations, etc. The theoretical study of the electron structure of disordered crystals, amorphous materials and liquids, monotomic and molecular alloys rests mainly in semiempirical rules or ad hoc theoretical models. The study of non-crystalline materials through the use of more realistic Hamiltonians is now of basic importance not only to understand optical and electrical properties as such, but also to explain chemical behavior in solids and liquids, catalysis, clustering, etc. as well as cluster and molecular magnetism.
