A Temporal Decoupling Strategy for Controlled Synthesis of 2D TbOBr and Moiré Superlattices

1), and exceptional ambient stability. Notably, we constructed the first rare-earth-based twisted van der Waals structures, revealing uniform square moiré superlattices covering the full range of twist angles (0°-45°). This work provides new insights into rare-earth material synthesis and establishes a robust materials platform for exploring two-dimensional rare-earth moiré physics, extending twistronics into f-electron systems.
