Sub-5 nm high-entropy nanoalloys beyond the hume-rothery limit

Yiqian Du, Xiaodi Zhou, Bangxin Li, Zhizhong Wang et autres

Lattice mismatch has long constrained alloy compositional design. Governed by the Hume-Rothery rules, severe atomic radius differences (δ) between the constituent elements of nano-alloys can lead to excessive lattice distortions or even phase separation. Therefore, synthesizing alloy nanoparticles with large δ-factors (>15%) …
