Electric Field-Induced Hole- and Electron-Type Flat Bands in Twisted Double Bilayer Graphene
Zhihao Jiang, Dongkyu Lee, Alfred J. H. Jones +11
Application of a finite electric field and small twist angle between two graphene bilayers leads to widely tunable electronic structures that support emergent phenomena. Here, we m…
Beyond the Flat-Band Paradigm: Open Orbits as a Route to Correlated States in Dispersive Moiré Minibands
Zihao Wang, Pablo M. Perez-Piskunow, Calvin Pei Yu Wong +16
The realization of fractional Chern insulators has largely relied on isolated flat bands in complex bilayer or multilayer moiré systems with ideal quantum geometry. Whether such ph…
Layer-Number-Controlled Symmetry Breaking and Surface-State Transport in Rhombohedral Graphene Multilayers
Bosai Lyu, Jian Zheng, Kai Liu +12
Rhombohedral multilayer graphene hosts layer-polarized flat bands, providing an intriguing platform for correlated and topological electronic states; however, the role of layer num…
Commensuration torques in double-moiré twisted trilayer hexagonal boron nitride and graphene heterostructures
Youngju Park, Nicolas Leconte, Prathap Kumar Jharapla +3
We study commensuration-driven torques and angle locking in double-moiré trilayer hexagonal boron nitride (hBN) and graphene heterostructures using large-scale atomistic relaxation…
Supermoiré domain-resolved effective Hamiltonians and valley topology in helical multilayer graphene
Kyungjin Shin, Nicolas Leconte, Jeil Jung +1
Extending moiré graphene beyond twisted bilayers, helical trilayer graphene has shown topological bands and correlated states with reshaped moiré periodicity. Here we develop a the…
Atomistic substrate relaxation effects in the band gaps of graphene on hexagonal boron nitride
Jiaqi An, Nicolas Leconte, Srivani Javvaji +2
We assess the impact of atomistic substrate lattice relaxation schemes in the primary band gap at charge neutrality and the secondary valence band gap of graphene on hexagonal boro…
