Abstract

"The time evolution of the KLL Auger spectrum of carbon was considered to be an effective tool in the l study of the diffusion process of carbon on polycrystalline nickel. Although very simple in theory, the useful application of this procedure to the desired purpose required a deeper involvement in the understanding of the Auger process.

Integration and deconvolution techniques were necessary to gain access to the information contained in the derivative mode of the Auger signal.

Part I of the dissertation describes the experimental and analytical procedures that were used in the evaluation of the transition density function of carbon on different substrates.

Part II describes the study of the bulk-to-surface precipitation and surface diffusion of carbon on polycrystalline nickel. The evaluation of the kinetics of these processes involved the monitoring of the time evolution of the Auger carbon signal as a function of temperature and also a mathematical model in terms of an interface.

Part I and Part II will be submitted for publication to Surface Science"-- Introduction, p. 1
