Chemisorption and reactions of molecules on semiconductor surfaces
Abstract
Experimental measurements have been performed of adsorbed atoms and molecules on metal and semiconductor surfaces over a wide range of temperatures (20K - 100K) to identify the nature of bonding, the structure, reaction intermediates and reaction products. This has included simple hydrocarbon and organic molecules on Ni, Pd, Pt and Ag single-crystal surfaces. The techniques of UV photoemission, low energy electron diffraction and high resolution electron energy loss spectroscopy were used and further developed to extract new information. The electronically excited states of absorbates relevant to Surface Enhanced Raman and Surface Chemistry were also investigated. Later work on Si(111) surfaces included studies of oxidation, water adsorption and metallization.
