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…
Pressure induced gap modulation and topological transitions in twisted bilayer and double bilayer graphene
Xianqing Lin, Haotian Zhu, Jun Ni
We study the electronic and topological properties of fully relaxed twisted bilayer (TBG) and double bilayer (TDBG) graphene under perpendicular pressure. An approach has been prop…
Periodically Gated Bilayer Graphene as an Electronic Metamaterial
Xianqing Lin, David Tomanek
We study ballistic transport in periodically gated bilayer graphene as a candidate for a 2D electronic metamaterial. Our calculations use the equilibrium Green function formalism a…
