Here, the successful growth of flat hexagonal 2D phosphorus on Au(111) is reported. Starting from phosphorus linear chains at low coverage, a porous network and finally an extended 2D flat hexagonal (HexP) layer while increasing phosphorus deposition is formed. Using scanning tunneling microscopy/spectroscopy combined with ab initio calculations, the structure and electronic properties of the as-grown phosphorus structures are followed. The progressive formation of a phosphorus electronic band in the conduction band region is followed. More strikingly, a partial flatband that appears only on the HexP phase characterized by a sharp peak in the electronic spectrSmall (Weinheim an der Bergstrasse, Germany)Probing Surface-Mediated Electronic Coupling in Flat Hexagonal Phosphorus Nanostructures and Monolayer on Au(111).PMC11657019ANR‐20‐CE09‐0023 DEFINE2DANR-20-CE09-0023 DEFINE2DANR-22-CE09-0022 2DPhostrainEANR‐22‐CE09‐0022 2DPhostrainESmogunov AKarn ALezoualc'h MMichel IELagoute JGirard YDappe YJChacon CfalseProbing Surface-Mediated Electronic Coupling in Flat Hexagonal Phosphorus Nanostructures and Monolayer on Au(111).Due to its diverse allotropes and intriguing properties, 2D phosphorus, also known as phosphorene, is a material of great interest.
