From Stripes to Hexagons: Strain‐Induced 2D Pb Phases Confined Between Graphene and SiC
Advanced Materials Interfaces, Volume 12, Issue 21, November 10, 2025.Intercalating Pb beneath epitaxial graphene on SiC(0001) stabilizes distinct 2D phases at the interface. Using LEED, LEEM, SEM, and STM, the formation of characteristic stripe and hexagonal Pb monolayer structures is observed, and atomistic models are provided.
