Quantum Parity Hall effect in ABA Graphene
Petr Stepanov, Yafis Barlas, Shi Che +10
The celebrated phenomenon of quantum Hall effect has recently been generalized from transport of conserved charges to that of other approximately conserved state variables, includi…
Twist Angle-Dependent Bands and Valley Inversion in 2D Materials/hBN Heterostructures
Shi Che, Petr Stepanov, Supeng Ge +13
The use of relative twist angle between adjacent atomic layers in a van der Waals heterostructure, has emerged as a new degree of freedom to tune electronic and optoelectronic prop…
Large tunable intrinsic gap in rhombohedral-stacked tetralayer graphene
K. Myhro, S. Che, Y. Shi +5
In rhombohedral-stacked few-layer graphene, the very flat energy bands near the charge neutrality point are unstable to electronic interactions, giving rise to states with spontane…
Topological nodal-line fermions in ZrSiSe and ZrSiTe
Jin Hu, Zhijie Tang, Jinyu Liu +8
The discovery of topological semimetal phase in three-dimensional (3D) systems is a new breakthrough in topological material research. Dirac nodal-line semimetal is one of the thre…
Generation of photovoltage in graphene on a femtosecond time scale through efficient carrier heating
Klaas-Jan Tielrooij, Lukasz Piatkowski, Mathieu Massicotte +8
Graphene is a promising material for ultrafast and broadband photodetection. Earlier studies addressed the general operation of graphene-based photo-thermoelectric devices, and the…
Multicomponent Quantum Hall Ferromagnetism and Landau Level Crossing in Rhombohedral Trilayer Graphene
Y. Lee, D. Tran, K. Myhro +6
Using transport measurements, we investigate multicomponent quantum Hall (QH) ferromagnetism in dual-gated rhombohedral trilayer graphene (r-TLG), in which the real spin, orbital p…
Distinct Competing Ordered ν=2 States in Bilayer Graphene
J. Velasco, Y. Lee, Fan Zhang +6
Because of its large density-of-states and the 2π Berry phase near its low-energy band-contact points, neutral bilayer graphene (BLG) at zero magnetic field (B) is susceptible to c…
Giant Interaction-Induced Gap and Electronic Phases in Rhombohedral Trilayer Graphene
Y. Lee, D. Tran, K. Myhro +7
Due to their unique electron dispersion and lack of a Fermi surface, Coulomb interactions in undoped two-dimensional Dirac systems, such as single, bi- and tri-layer graphene, can…
Transport in Suspended Monolayer and Bilayer Graphene Under Strain: A New Platform for Material Studies
Hang Zhang, Jhao-Wun Huang, Jairo Velasco +9
We develop two types of graphene devices based on nanoelectromechanical systems (NEMS), that allows transport measurement in the presence of in situ strain modulation. Different mo…
Broken Symmetry Quantum Hall States in Dual Gated ABA Trilayer Graphene
Yongjin Lee, Jairo Velasco, David Tran +6
We present low temperature transport measurements on dual-gated suspended trilayer graphene in the quantum Hall (QH) regime. We observe QH plateaus at filling factors ν=-8, -2, 2,…
