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…
Influence of sulphur vacancies on ultrafast charge separation in WS-graphene heterostructures
Johannes Gradl, Niklas Hofmann, Leonard Weigl +6
Understanding how defects influence charge separation in WS-graphene heterostructures is crucial for future applications in light harvesting and detection. Previous studies hav…
Phason-driven temperature-dependent transport in moiré graphene
Alex Boschi, Alejandro Ramos-Alonso, Vaidotas Mišeikis +9
The electronic and vibrational properties of 2D materials are dramatically altered by the formation of a moiré superlattice. The lowest-energy phonon modes of the superlattice are…
Influence of doping on non-equilibrium carrier dynamics in graphene
Leonard Weigl, Johannes Gradl, Peter Richter +5
Controlling doping is key to optimizing graphene for high-speed electronic and optoelectronic devices. However, its impact on non-equilibrium carrier lifetimes remains debated. Her…
Influence of excitation energy on microscopic quantum pathways for ultrafast charge transfer in van der Waals heterostructures
Niklas Hofmann, Johannes Gradl, Leonard Weigl +3
Efficient charge separation in van der Waals (vdW) heterostructures is crucial for optimizing light harvesting and detection applications. However, precise control over the microsc…
