| Abstract Scope |
Void superlattices have been known to form in materials under irradiation for decades. Although the exact mechanisms of such lattice ordering remain debated in the literature, recent theoretical and experimental studies have clarified the role of one-dimensional self-interstitial atoms diffusion in the superlattice formation process. Based on the framework developed in earlier modeling works, the present study aims at providing a deeper understanding of the dependance of several key superlattice properties on irradiation conditions, by combining theoretical analysis and Kinetic Monte-Carlo simulations. The results suggest that superlattice properties such as the lattice constant, ordering, and critical dose and temperature limit of formation are clearly correlated with irradiation condition parameters such as dose rate and temperature. The correlations elucidated by theory and simulations provide deeper insights regarding superlattice formation and constitute a valuable step towards the development of tailor-made meta-materials. |
