Abstract:

The equipment purchased is to be used in an experimental study of the relationship between atomic structure and chemical reactivity for boron and carbon surfaces. This research is currently being supported by grant AFOSR-88- 0111. A renewal proposal is currently pending with AFOSR to continue these studies. Carbon and boron are exceptionally stable, covalently bonded solids with highly unique crystal structures. The specific reactions to be studied are loosely related to the problems of oxidation and oxidation inhibition of carbon carbon composites. The main experimental instrument to be used is a scanning tunneling microscope STM purchased under grant number AFSOR-89-0146. Other techniques to be used include Auger electron spectroscopy, X-ray photoelectron spectroscopy XPS, ultraviolet photoelectron spectroscopy UPS, low energy electron diffraction LEED, temperature programmed desorption TPD and scanning tunneling microscopy STM.
