This work presents an atomic-level mapping of the structures formed upon deposition of phosphorus on a Cu(111) single-crystal under ultra-high vacuum conditions. A comprehensive overview of the current advancements in the synthesis of black and blue phosphorene is provided, encompassing both experimental preparation techniques and predictions of degradation processes. The analysis employs atomically-resolved scanning tunneling microscopy and spectroscopy to examine three distinct structures characterized by varying levels of phosphorus coverage. Remarkably, this investigation succeeds in identifying a large-scale single-layer blue phosphorene. Furthermore, an in-situ examination of the stability of these structures is conducted, revealing the rapid degradation of blue phosphorene even within an ultra-high vacuum environment.
