Emergence of bulk-like structural features and 2D-to-3D transition in boron nanoclusters

Proceedings of the National Academy of Sciences, Volume 122, Issue 47, November 2025. <br/>SignificanceInvestigation of the size-dependent properties in nanoclusters laid the foundation for nanoscience. Boron clusters are found to be planar, leading to the discovery of borophenes—a new class of synthetic 2D materials. A long-sought question in …
