Direct observation of flat bands in near-magic-angle twisted bilayer CVD graphene
Gianluigi Baiardi, Alex Boschi, Giulia Piccinini +13
Advances in chemical vapor deposition (CVD) growth have driven graphene crystal quality to unprecedented levels, yet it is still unknown whether this route can realize the fragile…
Lifshitz transitions and isospin polarization in twist-decoupled monolayer-bilayer graphene
Alex Boschi, Leonardo Sabattini, Sergey Slizovskiy +10
Bernal-stacked bilayer graphene (BLG) hosts correlated electronic phases tied to low-energy Lifshitz transitions at saddle points in its valence band. To access this regime, ultral…
Scanning Gate Microscopy Modulation of Supercurrent in Graphene Josephson Junctions
Ivan Villani, Samuele Fracassi, Niccolò Traverso Ziani +9
Graphene Josephson junctions represent an excellent platform for quantum technologies, thanks to the combination of high carrier mobility, ballistic transport, and large gate-tunab…
Quasi--periodic supercurrent at quantum Hall transitions
Ivan Villani, Matteo Carrega, Alessandro Crippa +9
The combination of superconductivity and quantum Hall (QH) effect is regarded as a key milestone in advancing topological quantum computation in solid-state systems. Recent quantum…
Built-in Bernal gap in large-angle-twisted monolayer-bilayer graphene
Alex Boschi, Zewdu M. Gebeyehu, Sergey Slizovskiy +9
Atomically thin materials offer multiple opportunities for layer-by-layer control of their electronic properties. While monolayer graphene (MLG) is a zero-gap system, Bernal-stacke…
Probing enhanced electron-phonon coupling in graphene by infrared resonance Raman spectroscopy
Tommaso Venanzi, Lorenzo Graziotto, Francesco Macheda +16
We report on resonance Raman spectroscopy measurements with excitation photon energy down to 1.16 eV on graphene, to study how low-energy carriers interact with lattice vibrations.…
