Effect of kinks and concerted diffusion mechanisms on mass transport and growth on stepped metal surfaces

Recent development in theoretical investigations using computer simulation techniques and the embedded atom method (EAM) on diffusion processes critical to nucleation and growth of thin films at fcc metal surfaces is reviewed. Through these investigations, interactions between adatoms and substrate, adatoms and steps, and clusters and substrate and the effect of these interactions on dynamic diffusion processes are further understood. The results from these theoretical investigations are generally consistent with available experimental data and have provided explanations for some experimental observations. Some predictions made a few years ago from these studies have been confirmed by the latest experiments.

And Diffusion

The study of defect formation at metal surfaces is a fundamental problem in surface physics. An understanding of defect formation is pertinent to growth and diffusion mechanisms. In addition, surface roughening, faceting, and surface melting are all defect mediated phase transitions involving the formation of different topological defects. While the importance of defects at surfaces is well recognized, the study of surface defects has been hampered by the lack of sufficiently accurate experimental techniques. In fact, it is only in the past 6 years that experiments on the thermal generation of defects on metal surfaces have been performed. This review attempts to outline both the theoretical and experimental work on surface defect formation on metal systems.

Observational Techniques

The focus of discussion in Working Group 3 was on the Thermodynamic Properties as determined spectroscopically, including the observational techniques and the theoretical modeling of physical processes responsible for the emission spectrum. Recent advances in observational techniques and theoretical concepts make this discussion particularly timely. It is wise to remember that the determination of thermodynamic parameters is not an end in itself and that these are interesting chiefly for what they can tell us about the energetics and mass transport in prominences.
