Recent progress in the analysis of the properties of a simple tight binding Hamiltonian, appropriate to the study of the role of topological disorder in determining properties of amorphous semiconductors, is reviewed. The band structure generated by such a Hamiltonian for the diamond cubic structure is compared with a more realistic calculation for Ge.
