Selective binding and periodic arrangement of magic boron clusters on monolayer borophene.

ABSTRACT: The synthesis and characterization of small boron clusters with unique size and regular arrangement are crucial for boron chemistry and two-dimensional borophene materials. In this study, together with theoretical calculations, the joint molecular beam epitaxy and scanning tunneling microscopy experiments achieve the formation of unique B₅ clusters on monolayer borophene (MLB) on a Cu(111) surface. The B₅ clusters tend to selectively bind to specific sites of MLB with covalent boron-boron bonds in the periodic arrangement, which can be ascribed to the charge distribution and electron delocalization character of MLB and also prohibits nearby co-adsorption of B₅ clusters. Furthermore, the close-packed adsorption of B₅ clusters would facilitate the
