Helical Edge States and Quantum Phase Transitions in Tetralayer Graphene
Shi Che, Yanmeng Shi, Jiawei Yang +9
Helical conductors with spin-momentum locking are promising platforms for Majorana fermions. Here we report observation of two topologically distinct phases supporting helical edge…
Tunable van Hove Singularities and Correlated States in Twisted Trilayer Graphene
Yanmeng Shi, Shuigang Xu, Mohammed M. Al Ezzi +16
Understanding and tuning correlated states is of great interest and significance to modern condensed matter physics. The recent discovery of unconventional superconductivity and Mo…
Stacking Order in Graphite Films Controlled by Van der Waals Technology
Yaping Yang, Yi-Chao Zou, Colin R. Woods +10
In graphite crystals, layers of graphene reside in three equivalent, but distinct, stacking positions typically referred to as A, B, and C projections. The order in which the layer…
Imaging Quantum Spin Hall Edges in Monolayer WTe2
Yanmeng Shi, Joshua Kahn, Ben Niu +9
A two-dimensional (2D) topological insulator (TI) exhibits the quantum spin Hall (QSH) effect, in which topologically protected spin-polarized conducting channels exist at the samp…
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…
