From Stripes to Hexagons : Strain-Induced 2D Pb Phases Confined Between Graphene and SiC
The intercalation of metals beneath graphene offers a powerful route to stabilizing and protecting novel 2D phases. The epitaxial growth of Pb monolayers on SiC(0001), combined with the relatively large spacing of the suspended graphene, makes this system particularly distinctive. Using low-energy electron diffraction (LEED) and various microscopy techniques—including scanning electron microscopy
