Step geometry-guided growth of rhombohedral graphene.

Rhombohedral (ABC)-stacked graphene has emerged as a platform for exploring correlated and topological physics.

Rhombohedral (ABC)-stacked graphene has emerged as a platform for exploring correlated and topological physics. However, its large-scale, pure-phase synthesis has been hindered by intrinsic thermodynamic metastability and kinetic instability. In this work, we introduce a step…
