    • In models for amorphous semiconductors, the Hamiltonian can be written as H=  + T̂, where  accounts for the intracluster hopping and satisfies  2 = Â, i.e., it is a projection operator, and T̂ is the operator responsible for the hopping between nearest-neighbor clusters and satisfies T̂2 =I. These properties of  and T̂ endow the spectrum with dispersionless bands.
