Preparation of graphene bilayers on platinum by sequential chemical vapour deposition
Johannes Halle, Alexander Mehler, Nicolas Néel +1
A cheap and flexible method is introduced that enables the epitaxial growth of bilayer graphene on Pt(111) by sequential chemical vapour deposition. Extended regions of two stacked…

Tailoring Intercalant Assemblies at the Graphene-Metal Interface
Johannes Halle, Nicolas Néel, Jörg Kröger
The influence of graphene on the assembly of intercalated material is studied using low-temperature scanning tunneling microscopy. Intercalation of Pt under monolayer graphene on P…

Understanding and engineering phonon-mediated tunneling into graphene on metal surfaces
J. Halle, N. Néel, M. Fonin +2
Metal-intercalated graphene on Ir(111) exhibits phonon signatures in inelastic elec- tron tunneling spectroscopy with strengths that depend on the intercalant. Extraor- dinarily st…
