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…
Magneto-spectroscopy of exciton Rydberg states in a CVD grown WSe2 monolayer
A. Delhomme, G. Butseraen, B. Zheng +9
The results of magneto-optical spectroscopy investigations of excitons in a CVD grown monolayer of WSe2 encapsulated in hexagonal boron nitride are presented. The emission linewidt…
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…
