We investigate the influence of SiO2, Au, Ag, Cu, and Pt substrates on the Raman spectrum of graphene. Experiments reveal particularly strong modifications to the intensity, position, width, and shape of the Raman signal of graphene on platinum, compared to that of suspended graphene. The modifications strongly depend on the relative orientation of the graphene and platinum lattices. These observations are theoretically investigated and shown to originate from hybridization of electronic states…

Hole doping, hybridization gaps, and electronic correlation in graphene on a platinum substrate.
TLDR
An angle-resolved photoemission study on the interaction between graphene and a platinum substrate and single out graphene/platinum as a model system investigating graphene on a metallic substrate with strong interaction is presented.

Efficient n-type doping in epitaxial graphene through strong lateral orbital hybridization of Ti adsorbate
Abstract In recent years, various doping methods for epitaxial graphene have been demonstrated through atom substitution and adsorption. Here we observe by angle-resolved photoemission spectroscopy
Surface-induced hybridization between graphene and titanium.
TLDR
This work experimentally investigates the structural interactions between graphene and transition metals such as palladium (Pd) and titanium (Ti), which have been confirmed by density functional simulations and shows that a surface induced p-d hybridization occurs between atomic carbon and titanium orbitals.
Tunable Kondo Resonance at a Pristine Two-Dimensional Dirac Semimetal on a Kondo Insulator.
TLDR
A resonance-type many-body ground state in graphene, a nonmagnetic two-dimensional Dirac semimetal, when grown on SmB6, a Kondo insulator, via thermal decomposition of fullerene molecules is demonstrated.
Temperature and face dependent copper–graphene interactions
Abstract The interaction between graphene and metals represents an important issue for the large-area preparation of graphene, graphene transfer and the contact quality in graphene devices. We
Proximity-induced spin-orbit effects in graphene on Au
We introduce a $p_{z}-d$ coupling model Hamiltonian for the $\pi$-graphene/Au bands that predicts a rather large intrinsic spin-orbit (SO) coupling as are being reported in recent experiments and DFT
Oxygen intercalation in PVD graphene grown on copper substrates: A decoupling approach
TLDR
The intercalation process of oxygen in-between a PVD-grown graphene layer and different copper substrates as a methodology for reducing the substrate-layer interaction leads to an extended defect-free graphene layer that strongly couples with the substrate.
Electroinduced Intercalation of Tetraalkylammonium Ions at the Interface of Graphene Grown on Copper, Platinum, and Iridium
Electrochemically driven intercalation of tetraalkylammonium ions can facilitate the delamination of graphene films fabricated by chemical vapour deposition (CVD) from their supporting metal catalyst
Au concentration-dependent quenching of Raman 2D peak in graphene
We investigate the effect of sputtered gold nanoclusters (AuNCs) on the Raman spectra of graphene. The two prominent Raman peaks of graphene – 2D and G – show drastically different behaviour with
