Blue phosphorus, a previously unknown phase of has been recently predicted by theoretical calculations and shares its layered structure high stability with black rapidly rising two-dimensional material. Here, we report molecular beam epitaxial growth single layer blue phosphorus on Au(111) using as precursor, through the combination in situ low temperature scanning tunneling microscopy density functional theory calculation. The as-grown is explained (4 × 4) unit cell coinciding (5 5) cell, this verified calculations. electronic bandgap determined to be 1.10 eV spectroscopy measurement. realization large-scale quality atomic-layered can enable rapid development novel optoelectronic devices based emerging
