Wafer-scale integration of graphene-based photonic devices
Marco A. Giambra, Vaidotas Mišeikis, Sergio Pezzini +7
Graphene and related materials can lead to disruptive advances in next generation photonics and optoelectronics. The challenge is to devise growth, transfer and fabrication protoco…
Ultrafast, Zero-Bias, Graphene Photodetectors with Polymeric Gate Dielectric on Passive Photonic Waveguides
Vaidotas Mišeikis, Simone Marconi, Marco A. Giambra +15
We report compact, scalable, high-performance, waveguide integrated graphene-based photodetectors (GPDs) for telecom and datacom applications, not affected by dark current. To expl…
Synthesis of large-area rhombohedral few-layer graphene by chemical vapor deposition on copper
Chamseddine Bouhafs, Sergio Pezzini, Neeraj Mishra +6
Rhombohedral-stacked few-layer graphene (FLG) has been receiving an ever-increasing attention owing to its peculiar electronic properties that could lead to enticing phenomena such…
High-quality electrical transport using scalable CVD graphene
Sergio Pezzini, Vaidotas Mišeikis, Simona Pace +4
Producing and manipulating graphene on fab-compatible scale, while maintaining its remarkable carrier mobility, is key to finalize its technological application. We show that a lar…
High-speed double layer graphene electro-absorption modulator on SOI waveguide
Marco A. Giambra, Vito Sorianello, Vaidotas Miseikis +6
We report on a C-band double layer graphene electro-absorption modulator on a passive SOI platform showing 29GHz 3dB-bandwith and NRZ eye-diagrams extinction ratios ranging from 1.…
Determination of the Fermi surface and field-induced quasi-particle tunneling around the Dirac nodal-loop in ZrSiS
C. S. A. Müller, T. Khouri, M. R. van Delft +8
Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semi-metals, but only in a relatively…
30-twisted bilayer graphene quasicrystals from chemical vapor deposition
Sergio Pezzini, Vaidotas Miseikis, Giulia Piccinini +8
The artificial stacking of atomically thin crystals suffers from intrinsic limitations in terms of control and reproducibility of the relative orientation of exfoliated flakes. Thi…
