Fig. 2.

Structural features of the BCC crystal for the simulation with a static (A, D, and G) and a dynamic (B, E, and H) base crystal and the experiments (C, F, and I). (A–C) Snapshots of BCC crystals at $\varphi =0.14$, in which particles are color coded according to their instantaneous bond-order parameter ${\overline{q}}_6$ and dopant particles are rendered in orange (A and B only). (D–F) Pair correlation functions $g(r)$. (G–I) Potential energy landscape through four unit cells within the on-average ordered lattice, where black disks indicate the hard-sphere radius of the base crystal particles and the gray areas indicate the volume, from which the center of mass of dopants is excluded, due to dopant–base particle overlap.
