N2 - The electronic structure of hydrogenated amorphous Silicon is studied as a function of hydrogen concentration, and of local configurations. The theory used for the calculations is based on a Cluster-Bethe lattice method, using a tight-binding Hamiltonian. The alloy disorder is treated with a theory, based on the Coherent Potential Approximation (CPA), which is able to introduce effects of different local configurations in the Bethe lattices through nested self-consistent solutions.
