Self-Aligned Metallic-Semiconducting Phosphorus Nanoarrays Driven by Facet Engineeringtranslating…

arXiv:2606.18907v1 Announce Type: new Abstract: Two-dimensional (2D) materials often require specific substrate terminations for epitaxial stabilization, yet the search for suitable templates has largely focused on low-index metal surfaces, which may not provide the optimal conditions for the growth of new phases. Here, we show that crystal-facet engineering on curved Cu surfaces enables the stabilization, within a single preparation step, of two distinct 2D phosphorus phases with different ele
