CHEMICAL BONDING OF ALLOY AND DOPANT ATOMS IN AMORPHOUS SILICONG. Lucovsky

The chemical bonding environments of Si and dopant atoms in alloys of a-Si are characterized through a local electronegativity. This parameter is used as a scaling variable for empirical relations based on molecular data : the chemical shifts in the frequencies of Si-H and Si-F local vibrations, and in the binding energies of Si 2p core states.
