Implication

Surface analysis reveals two predominant domain orientations during ethylene decomposition on Cu(111), highlighting domain boundary suppression as critical for material quality.

Key Points

To synthesize monolayer graphene on single-crystal Cu(111) and characterize its structural and electronic properties.
Synthesized graphene on single-crystal Cu(111) via thermal decomposition of ethylene inside an ultrahigh vacuum chamber.
Characterized atomic-scale structural morphology and electronic properties using scanning tunneling microscopy and scanning tunneling spectroscopy.
Observed the nucleation of monolayer graphene islands exhibiting two primary domain orientations on the substrate.
Documented extensive formation of domain boundaries as surface coverage increased, identifying boundary density reduction as a critical challenge for synthesis.
