| Abstract Scope |
Several routes have been developed in the past decades to improve radiation resistance in materials. Here I will discuss new approaches to modify formation and evolution of radiation induced defects in homogenous and heterogenous material systems. Thanks to positron annihilation spectroscopy (PAS), atomic scale defects formed following collision cascades at the early stages of damage can be probed and characterized revealing the mechanisms governing early formation of defects and their evolution even in extreme environments and paving the way to engineer new material systems.
In this work, through a combination of PAS, TEM, and atomistic simulations we show how we improve radiation tolerance by incorporating nanovoids and designing interfaces with specific features. Examples on improving radiation resistance in both structural and electronic materials will be presented.
