Abstract Scope |
We describe an ongoing effort to elucidate the effect of curvature on the radiation response of solid-state interfaces. This work integrates modeling and experiments to discover how curvature-induced behavior changes with interface structure. We begin by selecting a set of model heterophase interfaces that pair Cu with another FCC metal or with a BCC metal. We then develop a set of atomic potentials to describe all these binary systems. Transmission electron microscopy is used to investigate samples with highly curved interfaces after implantation with helium (He), focusing on the effect of composition and interface structure on the resulting He bubble microstructure. Work towards the convergence of experimental and modeling investigations will be discussed. |
