Abstract

, which was confirmed by circularly polarized Raman spectroscopy, and identified two 1D moiré superlattices near 58 and 61° via transmission electron microscopy. Geometrical analysis identifies six discrete critical twist angles that satisfy the intrinsic 1D condition. Our results establish racemic assembly as a general route to achieve intrinsic 1D moiré superlattices in planar-chiral 2D materials.
