Atomic-scale 3D insights into heteroepitaxial mechanisms in hcp/fcc, bcc/fcc, and fcc/fcc core-shell nanoparticles
{{output}}
Heteroepitaxy on nanocrystals of diverse crystal structures (hcp, bcc, or fcc) is a powerful approach for engineering atomic arrangements. However, the mechanisms by which interfacial defects and strain relaxation accommodate structural mismatch remain poorly ... ...
