Fermi resonance in the Raman spectrum of graphene
Dipankar Kalita, Michele Amato, Alexandre Artaud +6
We report the observation of an intense anomalous peak at 1608 cm in the Raman spectrum of graphene associated to the presence of chromium nanoparticles in contact with grap…
Anharmonicity in Raman-active phonon modes in atomically thin MoS
Suman Sarkar, Indrajit Maity, H. L. Pradeepa +10
Phonon-phonon anharmonic effects have a strong influence on the phonon spectrum; most prominent manifestation of these effects are the softening (shift in frequency) and broadening…
Interlayer Charge Transfer and Defect Creation in Type I van der Waals Heterostructures
G. Nayak, S. Lisi, W-L. Liu +13
Van der Waals heterostructures give access to a wide variety of new phenomena that emerge thanks to the combination of properties brought in by the constituent layered materials. W…
Coherence and density dynamics of excitons in a single-layer MoS reaching the homogeneous limit
Tomasz Jakubczyk, Goutham Nayak, Lorenzo Scarpelli +13
We measure the coherent nonlinear response of excitons in a single-layer of molybdenum disulphide embedded in hexagonal boron nitride, forming a -BN/MoS/-BN heterostructu…
Deviation from the normal mode expansion in a coupled graphene-nanomechanical system
Cornelia Schwarz, Benjamin Pigeau, Laure Mercier de Lépinay +6
We optomechanically measure the vibrations of a nanomechanical system made of a graphene membrane suspended on a silicon nitride nanoresonator. When probing the thermal noise of th…
Strain superlattices and macroscale suspension of Graphene induced by corrugated substrates
Antoine Reserbat-Plantey, Dipankar Kalita, Laurence Ferlazzo +11
We investigate the organized formation of strain, ripples and suspended features in macroscopic CVD-prepared graphene sheets transferred onto a corrugated substrate made of an orde…
Time- and Space-Modulated Raman Signals in Graphene-based Optical Cavities
Antoine Reserbat-Plantey, Svetlana Klyatskaya, Valerie Reita +5
We present fabrication and optical characterization of micro-cavities made of multilayer graphene (MLG) cantilevers clamped by metallic electrodes and suspended over Si/Si02 substr…
Suppression of Multilayer Graphene Patches during CVD Graphene growth on Copper
Zheng Han, Amina Kimouche, Adrien Allain +7
By limiting the carbon segregation at the copper surface defects, a pulsed chemical vapor deposition method for single layer graphene growth is shown to inhibit the formation of fe…
Local Optical Probe of Motion and Stress in a multilayer graphene NEMS
Antoine Reserbat-Plantey, Laetitia Marty, Olivier Arcizet +2
Nanoelectromechanical systems (NEMSs) are emerging nanoscale elements at the crossroads between mechanics, optics and electronics, with significant potential for actuation and sens…
First principles study of iron-based molecule grafted on graphene
Antoine Reserbat-Plantey, Paola Gava, Nedjma Bendiab +1
Motivated by recent experimental studies on single molecular magnets grafted on graphene and single walled carbon nanotubes, we investigate the structural, electronic, and magnetic…
Large and Flat Graphene Flakes Produced by Epoxy Bonding and Reverse Exfoliation of Highly Oriented Pyrolitic Graphite
Vincent Huc, Nedjma Bendiab, Noel Rosman +3
We present a fabrication method producing large and flat graphene flakes that have a few layers down to a single layer based on substrate bonding of a thick sample of highly orient…
