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…
Effect of the nanowire diameter on the linearity of the response of GaN-based heterostructured nanowire photodetectors
Maria Spies, Jakub Polaczyński, Akhil Ajay +5
Nanowire photodetectors are investigated because of their compatibility with flexible electronics, or for the implementation of on-chip optical interconnects. Such devices are char…
Sensing ion channels in neuronal networks with graphene transistors
Farida Veliev, Dipankar Kalita, Antoine Bourrier +5
Graphene, the atomically-thin honeycomb carbon lattice, is a highly conducting 2D material whose exposed electronic structure offers an ideal platform for sensing. Its biocompatibl…
High-Yield Proximity-Induced Chemical Vapor Deposition of Graphene Over Millimeter-Sized Hexagonal Boron Nitride
Hadi Arjmandi-Tash, Dipankar Kalita, Zheng Han +9
We present a transfer-free preparation method for graphene on hexagonal boron nitride (h-BN) crystals by chemical vapor deposition of graphene via a catalytic proximity effect, i.e…
Nanofaceting as a stamp for periodic graphene charge carrier modulations
M. Vondracek, M. Kucera, L. Fekete +6
The exceptional electronic properties of monoatomic thin graphene sheets triggered numerous original transport concepts, pushing quantum physics into the realm of device technology…
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…
Interplay between Raman shift and thermal expansion in graphene: temperature-dependent measurements and analysis of substrate corrections
S. Linas, Y. Magnin, B. Poinsot +12
Measurements and calculations have shown significant disagreement regarding the sign and variations of the thermal expansion coefficient (TEC) of graphene . Here we report de…
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…
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…
