Collective excitations of the Chern-insulator states in commensurate double moiré superlattices of twisted bilayer graphene on hexagonal boron nitride
Xianqing Lin, Quan Zhou, Cheng Li +1
We study the collective excitation modes of the Chern insulator states in magic-angle twisted bilayer graphene aligned with hexagonal boron nitride (TBG/BN) at odd integer fillings…
Energetic stability and spatial inhomogeneity in the local electronic structure of relaxed twisted trilayer graphene
Xianqing Lin, Cheng Li, Kelu Su +1
We study the energetic stability and the local electronic structure of the general twisted trilayer graphene (TTG) with the top and bottom layers rotated with respect to the middle…
Emergence of intrinsically isolated flat bands and their topology in fully relaxed twisted multi-layer graphene
Xianqing Lin, Haotian Zhu, Jun Ni
We study the electronic structure and band topology of fully relaxed twisted multi-layer graphene (TMLG). Isolated flat bands emerge in TMLG with the number of layers [ with $…
Moiré effects in graphene--hBN heterostructures
Yongping Du, Ning Xu, Xianqing Lin +1
Encapsulating graphene in hexagonal Boron Nitride has several advantages: the highest mobilities reported to date are achieved in this way, and precise nanostructuring of graphene…
Misalignment instability in magic-angle twisted bilayer graphene on hexagonal boron nitride
Xianqing Lin, Kelu Su, Jun Ni
We study the stability and electronic structure of magic-angle twisted bilayer graphene on the hexagonal boron nitride (TBG/BN). Full relaxation has been performed for commensurate…
Symmetry breaking in the double moiré superlattices of relaxed twisted bilayer graphene on hexagonal boron nitride
Xianqing Lin, Jun Ni
We study the atomic and electronic structures of the commensurate double moiré superlattices in fully relaxed twisted bilayer graphene (TBG) nearly aligned with the hexagonal boron…
