Resumen:
The density of states is calculated for a tight-binding model of amorphous Si and Ge which includes the effects of dihedral-angle disorder. The hopping parameters are calculated using the crystalline values. Though the model and the approximations made to solve it are very simple, the results agree with various features observed in photoemission experiments.
