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…
Phonon-mediated room-temperature quantum Hall transport in graphene
Daniel Vaquero, Vito Clericò, Michael Schmitz +14
The quantum Hall (QH) effect in two-dimensional electron systems (2DESs) is conventionally observed at liquid-helium temperatures, where lattice vibrations are strongly suppressed…
Moiré-Induced Transport in CVD-Based Small-Angle Twisted Bilayer Graphene
Giulia Piccinini, Vaidotas Mišeikis, Pietro Novelli +5
To realize the applicative potential of 2D twistronic devices, scalable synthesis and assembly techniques need to meet stringent requirements in terms of interface cleanness and tw…
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…
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…

S. Pezzini, S. Wiedmann, A. Mishchenko +5
We report on high-field magnetotransport (B up to 35 T) on a gated superlattice based on single-layer graphene aligned on top of hexagonal boron nitride. The large-period moiré mod…
High-order fractal states in graphene superlattices
R. Krishna Kumar, A. Mishchenko, X. Chen +7
Graphene superlattices were shown to exhibit high-temperature quantum oscillations due to periodic emergence of delocalized Bloch states in high magnetic fields such that unit frac…
Coexistence of bulk and surface states probed by Shubnikov-de Haas oscillations in BiSe with high charge-carrier density
E. K. de Vries, S. Pezzini, M. J. Meijer +6
Topological insulators are ideally represented as having an insulating bulk with topologically protected, spin-textured surface states. However, it is increasingly becoming clear t…
Quantum Transport in Ambipolar Few-layer Black Phosphorus
Gen Long, Denis Maryenko, Sergio Pezzini +10
Few-layer black phosphorus possesses unique electronic properties giving rise to distinct quantum phenomena and thus offers a fertile platform to explore the emergent correlation p…
Unconventional mass enhancement around the Dirac nodal loop in ZrSiS
S. Pezzini, M. R. van Delft, L. Schoop +5
The topological properties of fermions arise from their low-energy Dirac-like band dispersion and associated chiralities. Initially confined to points, extensions of the Dirac disp…
