Research Progress on Twistoptics in Moiré Superlattices

Abstract Moir superlattices in two-dimensional van der Waals heterostructures exhibit a wealth of physical phe nomena significantly expanding the research scope of twistoptics.By precisely tuning the interlayer twist angle Moir superlattices can generate unique electronic excitonic and optical properties such as band flattening strong correlation states topological states and chiral optical responses.These characteristics open new opportunities for novel optoelectronic devices single-photon sources exciton lasers and quantum computing platforms.This review systematically summarizes recent advances in twisted photonics of Moir superlattices covering the fabrication meth ods exciton behaviors nonlinear optical effects nanoscale spectroscopy and electric field tunability.The potential applications in future optoelectronics and quantum technologies are also discussed.
