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 relaxatio…

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…

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…
