Metal-phosphorus network on Pt(111)

Abstract

Phosphorus (P) has been predicted to possess many two-dimensional (2D) allotropes, which have attracted intensive research attention due to their excellent properties and application promises. While only 2D black P films have been successfully obtained by the exfoliation method, fabrication of other phosphorus structures by epitaxial growth remains challenging. Recently, the metal-phosphorus network (MPhoN), a superstructure consisted of P and metal atoms has been realized, which offers a wider platform to study P and related compounds. In this paper, we report the observation of platinum-phosphorus networks obtained by P adsorption on Pt(111). Our findings not only enrich the diverse structures of the MPhoN family but also provide insights into the formation mechanism of epitaxial P and its interaction with the noble metal substrate.
