Shear and breathing modes of layered materials
Giovanni Pizzi, Silvia Milana, Andrea C. Ferrari +2
Layered materials (LMs), such as graphite, hexagonal boron nitride, and transition-metal dichalcogenides, are at the centre of an ever increasing research effort, due to their scie…
Vertically-Illuminated, Resonant-Cavity-Enhanced, Graphene-Silicon Schottky Photodetectors
M. Casalino, U. Sassi, I. Goykhman +8
We report vertically-illuminated, resonant cavity enhanced, graphene-Si Schottky photodetectors (PDs) operating at 1550nm. These exploit internal photoemission at the graphene-Si i…
Microfluidization of graphite and formulation of graphene-based conductive inks
P. G. Karagiannidis, S. A. Hodge, L. Lombardi +12
We report the exfoliation of graphite in aqueous solutions under high shear rate [] turbulent flow conditions, with a 100\% exfoliation yield. The material is stabi…
Graphene-based, mid-infrared, room-temperature pyroelectric bolometers with ultrahigh temperature coefficient of resistance
U. Sassi, R. Parret, S. Nanot +9
Graphene is ideally suited for photonic and optoelectronic applications, with a variety of photodetectors (PDs) in the visible, near-infrared (NIR), and THz reported to date, as we…
Raman fingerprints of atomically precise graphene nanoribbons
Ivan A. Verzhbitskiy, Marzio De Corato, Alice Ruini +12
Bottom-up approaches allow the production of ultra-narrow and atomically precise graphene nanoribbons (GNRs), with electronic and optical properties controlled by the specific atom…

Ilya Goykhman, Ugo Sassi, Boris Desiatov +8
We report an on-chip integrated metal-graphene-silicon plasmonic Schottky photodetector with 85mA/W responsivity at 1.55 um and 7% internal quantum efficiency. This is one order of…

T. J. Echtermeyer, S. Milana, U. Sassi +4
The combination of plasmonic nanoparticles and graphene enhances the responsivity and spectral selectivity of graphene-based photodetectors. However, the small area of the metal-gr…
Interface coupling in twisted multilayer graphene by resonant Raman spectroscopy of layer breathing modes
Jiang-Bin Wu, Zhi-Xin Hu, Xin Zhang +9
Raman spectroscopy is the prime non-destructive characterization tool for graphene and related layered materials. The shear (C) and layer breathing modes (LBMs) are due to relative…
Few-cycle pulses from a graphene mode-locked all-fiber laser

T. J. Echtermeyer, P. S. Nene, M. Trushin +8
Graphene's high mobility and Fermi velocity, combined with its constant light absorption in the visible to far-infrared range, make it an ideal material to fabricate high-speed and…
