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…
High Responsivity, Large-Area Graphene/MoS2 Flexible Photodetectors
D. De Fazio, I. Goykhman, M. Bruna +9
We present flexible photodetectors (PDs) for visible wavelengths fabricated by stacking centimetre-scale chemical vapour deposited (CVD) single layer graphene (SLG) and single laye…
On-chip integrated, silicon-graphene plasmonic Schottky photodetector, with high responsivity and avalanche photogain
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…
Surface plasmon polariton graphene photodetectors
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…
Photo-thermoelectric and photoelectric contributions to light detection in metal-graphene-metal photodetectors
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…
Controlling Sub-nm Gaps in Plasmonic Dimers using Graphene
Jan Mertens, Anna L. Eiden, Daniel O. Sigle +9
Graphene is used as the thinnest possible spacer between gold nanoparticles and a gold substrate. This creates a robust, repeatable, and stable sub-nanometre gap for massive plasmo…
