Process for Creating Plumbene, a 2D Monolayer of Lead Atoms

Caption

Plumbene is realized by annealing an ultrathin lead (Pb) film on palladium Pd(111). The resulting surface material has the signature honeycomb structure of a 2D monolayer, as revealed by scanning tunneling microscopy. Surprisingly, beneath the plumbene, a palladium-lead (Pd-Pb) alloy thin film forms with a bubble structure (Fig. 4 (a)) reminiscent of a Weaire-Phelan structure, which was the inspiration for the design of the Beijing National Aquatics Centre ("Water Cube") of the 2008 Olympics in Beijing.
