Unexpected Zero Bias Conductance Peak on the Topological Semimetal Sb(111) with a Broken Bilayer
Yau-Chuen Yam, Shiang Fang, Pengcheng Chen +9
The long-sought Majorana fermion is expected to manifest in a topological-superconductor heterostructure as a zero bias conductance peak (ZBCP). As one promising platform for such…
Observation of the nonlinear Hall effect under time reversal symmetric conditions
Qiong Ma, Su-Yang Xu, Huitao Shen +18
The electrical Hall effect is the production of a transverse voltage under an out-of-plane magnetic field. Historically, studies of the Hall effect have led to major breakthroughs…
Dihedral-angle-corrected registry-dependent interlayer potential for multilayer graphene structures
Mingjian Wen, Stephen Carr, Shiang Fang +2
The structural relaxation of multilayer graphene is essential in describing the interesting electronic properties induced by intentional misalignment of successive layers, includin…
High performance Tunnel Field Effect Transistors based on in-plane transition metal dichalcogenide heterojunctions
Jean Choukroun, Marco Pala, Shiang Fang +2
In-plane heterojunction tunnel field effect transistors based on monolayer transition metal dichalcogenides are studied by means of self-consistent non-equilibrium Green's function…
Pressure dependence of the magic twist angle in graphene superlattices
Stephen Carr, Shiang Fang, Pablo Jarillo-Herrero +1
The recently demonstrated unconventional superconductivity in twisted bilayer graphene (tBLG) opens the possibility for interesting applications of two-dimensional layers that invo…
Berry curvature dipole current in transition metal dichalcogenides family
Jhih-Shih You, Shiang Fang, Su-Yang Xu +2
We study the quantum nonlinear Hall effect in two-dimensional materials with time-reversal symmetry. When only one mirror line exists, a transverse charge current occurs in second-…
Atomic and electronic reconstruction at van der Waals interface in twisted bilayer graphene
Hyobin Yoo, Rebecca Engelke, Stephen Carr +14
Control of the interlayer twist angle in two-dimensional (2D) van der Waals (vdW) heterostructures enables one to engineer a quasiperiodic moiré superlattice of tunable length scal…
Magic-angle graphene superlattices: a new platform for unconventional superconductivity
Yuan Cao, Valla Fatemi, Shiang Fang +4
The understanding of strongly-correlated materials, and in particular unconventional superconductors, has puzzled physicists for decades. Such difficulties have stimulated new rese…
Correlated Insulator Behaviour at Half-Filling in Magic Angle Graphene Superlattices
Yuan Cao, Valla Fatemi, Ahmet Demir +9
Van der Waals (vdW) heterostructures are an emergent class of metamaterials comprised of vertically stacked two-dimensional (2D) building blocks, which provide us with a vast tool…
