- Abstract
- Angle-resolved photoemission spectroscopy, low-energy electron diffraction, and density functional theory calculations were employed to investigate the electronic and structural properties of a graphene layer grown on the regularly stepped Pt(997) surface. The measurements show the predominance of a (2×2) multidomain superstructure of graphene, lying flat on the Pt terraces and covering the step edges in a carpetlike mode. The linearly dispersing ? band of graphene appears to be weakly affected by the substrate at the K point, while an appreciable hybridization is found at the ? point. Replicas of the Dirac cone are seen perpendicularly to the steps, with double real-space periodicity compared to the Pt terrace width. © 2014 American Physical Society. (literal)
