Geometric control of the moire twist angle in heterobilayer flakes
Prathap Kumar Jharapla, Nicolas Leconte, Zhiren He +2
We demonstrate a finite twist-angle stabilization mechanism in lattice-mismatched 2D heterobilayers, which results from the geometric alignment between the flake edges and its moir…
Near room temperature magnetoelectric response and tunable magnetic anisotropy in the two-dimensional magnet 1T-CrTe2
Fengping Li, Bheema Lingam Chittari, Chao Lei +1
Magnets with controllable magnetization and high critical temperature are essential for practical spintronics devices, among which the two-dimensional 1T-CrTe2 stands out because o…
Optical control of the moiré twist angle
Zhiren He, Prathap Kumar Jharapla, Nicolas Leconte +2
In this theoretical work, we propose an all-optical method for fast, precise manipulation of two-dimensional multilayers by transferring orbital angular momentum from phase-structu…
Moiré exciton polaron engineering via twisted hBN
Minhyun Cho, Biswajit Datta, Kwanghee Han +11
Twisted hexagonal boron nitride (thBN) exhibits emergent ferroelectricity due to the formation of moiré superlattices with alternating AB and BA domains. These domains possess ele…
Ab initio tight-binding Models for Mono- and Bilayer Hexagonal Boron Nitride (h-BN)
Srivani Javvaji, Fengping Li, Jeil Jung
Hexagonal boron nitride (-BN) exhibits dominant -bands near the Fermi level, similar to graphene. However, unlike graphene, where tight-binding (TB) models accurately re…
Moiré flat bands and antiferroelectric domains in lattice relaxed twisted bilayer hexagonal boron nitride under perpendicular electric fields
Fengping Li, Dongkyu Lee, Nicolas Leconte +2
Local interlayer charge polarization of twisted bilayer hexagonal boron nitride (t2BN) is calculated and parametrized as a function of twist angle and perpendicular electric fields…
