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…
Tunable Lifshitz Transitions and Multiband Transport in Tetralayer Graphene
Yanmeng Shi, Shi Che, Kuan Zhou +8
As the Fermi level and band structure of two-dimensional materials are readily tunable, they constitute an ideal platform for exploring Lifshitz transition, a change in the topolog…
Energy gaps and layer polarization of integer and fractional quantum Hall states in bilayer graphene
Yanmeng Shi, Yongjin Lee, Shi Che +6
Owing to the spin, valley, and orbital symmetries, the lowest Landau level (LL) in bilayer graphene exhibits multicomponent quantum Hall ferromagnetism. Using transport spectroscop…
