Cini-Sawatzky's Model in Studies of Electrodeposited Ni-Mo Alloys with Polymers

Abstract

Electronic structures of electrodeposited Ni-Mo layers with polyethylene, polytiophene and polypyrrole were studied by Auger electron spectroscopy using the Cini-Sawatzky's model. Comparison of the theoretical and experimental lines was carried out using the asymmetry parameter of the spectral lines. It is pointed out that the changes of the spectral main lines Ni and Mo are connected with the ways of polymerization. It has been also shown that the application of the Cini-Sawaztky model to the experimental spectral lines can be used to explain the distortion appearing in the materials. Model parameters, i.e., intra-atomic correlation and bandwidth were determined.
