Impact of the angular alignment on the crystal field and intrinsic doping of bilayer graphene/BN heterostructures
L. S. Farrar, G. Maffione, V. -H. Nguyen +5
The ability to tune the energy gap in bilayer graphene makes it the perfect playground for the study of the effects of internal electric fields, such as the crystalline field, whic…
Quantifying the local mechanical properties of twisted double bilayer graphene
Alessandra Canetta, Sergio Gonzalez-Munoz, Viet-Hung Nguyen +13
Nanomechanical measurements of minimally twisted van der Waals materials remained elusive despite their fundamental importance for device realisation. Here, we use Ultrasonic Force…
Paramagnetic singularities of the orbital magnetism in graphene with a moiré potential
J. Vallejo Bustamante, R. Ribeiro-Palau, C. Fermon +9
The recent detection of the singular diamagnetism of Dirac electrons in a single graphene layer paved a new way of probing 2D quantum materials through the measurement of equilibri…
Non-identical moiré twins in bilayer graphene
E. Arrighi, V. -H. Nguyen, M. Di Luca +8
The superlattice obtained by aligning a monolayer graphene and boron nitride (BN) inherits from the hexagonal lattice a sixty degrees periodicity with the layer alignment. It impli…
Heat equilibration of integer and fractional quantum Hall edge modes in graphene
Gaëlle Le Breton, Raphaëlle Delagrange, Yuanzhuo Hong +7
Hole-conjugate states of the fractional quantum Hall effect host counter-propagating edge channels which are thought to exchange charge and energy. These exchanges have been the su…
High quality electrostatically defined hall bars in monolayer graphene
Rebeca Ribeiro-Palau, Shaowen Chen, Yihang Zeng +4
Realizing graphene's promise as an atomically thin and tunable platform for fundamental studies and future applications in quantum transport requires the ability to electrostatical…
Competing Fractional Quantum Hall and Electron Solid Phases in Graphene
Shaowen Chen, Rebeca Ribeiro-Palau, Kang Yang +5
We report experimental observation of the reentrant integer quantum Hall effect in graphene, appearing in the N2 Landau level. Similar to high-mobility GaAs/AlGaAs heterostructu…
Twistable electronics with dynamically rotatable heterostructures
Rebeca Ribeiro-Palau, Changjian Zhang, Kenji Watanabe +3
The electronic properties of two-dimensional materials and their heterostructures can be dramatically altered by varying the relative angle between the layers. This makes it theore…
Graphene surpasses GaAs/AlGaAs for the application of the quantum Hall effect in metrology
R. Ribeiro-Palau, F. Lafont, J. Brun-Picard +8
The quantum Hall effect (QHE) theoretically provides a universal standard of electrical resistance in terms of the Planck constant and the electron charge . In graphene, the…
Quantum Hall resistance standards from graphene grown by chemical vapor deposition on silicon carbide
F. Lafont, R. Ribeiro-Palau, D. Kazazis +9
Replacing GaAs by graphene to realize more practical quantum Hall resistance standards (QHRS), accurate to within in relative value, but operating at lower magnetic field…
Anomalous dissipation mechanism and Hall quantization limit in polycrystalline graphene grown by chemical vapor deposition
F. Lafont, R. Ribeiro-Palau, Z. Han +8
We report on the observation of strong backscattering of charge carriers in the quantum Hall regime of polycrystalline graphene grown by chemical vapor deposition, which alters the…
