Ultra‐Large‐Period Moiré Lattices in Twisted Trilayer MoS 2 Induced by High‐Symmetry Sites

, hierarchically composed of periodical mirror-symmetric triangular tessellation patterns consisting of five kinds of high-symmetric stacking registrations and the relaxation regions resulting from the interlayer gliding. This robust ultra-large-period superstructure generates a deep moiré potential to effectively suppress intralayer moiré excitons recombination and be against intervalley exchange interaction at the magnetic field up to 9T, associated with the enhanced layer-valley-locked polarization by two-fold larger than that of the trilayer systems with incommensurate angles. Our work presents angle-dependent super-moiré architectures in Tt systems as a versatile platform for designing moiré quantum materials with tailored optoelectronic responses, advancing applications in valleytronic and excitonic devices.
