Center for Surface Radiation Damage Studies

Abstract

Identifying the surface damage process, we studied two systems in some depth, TiO2 and NiO. In TiO2 there is a phase transition to TiO which spreads from the surface and is driven by oxygen desorption. This work provided the first indications that diffusion was the rate limiting step. In NiO there is no DIET, but knockon damage at higher voltages and two electron beam stimulated reaction one of which abstracts nickel and another reduction by carbon contaminants. (eg)
