摘要

Moir?? superlattices, the artificial quantum materials, have provided a wide range of possibilities for the exploration of completely new physics and device architectures. In this Review, we focus on the recent progress on emerging moir?? photonics and optoelectronics, including but not limited to moir?? excitons, trions, and polaritons; resonantly hybridized excitons; reconstructed collective excitations; strong mid-and far-infrared photoresponses; terahertz single-photon detection; and symmetry-breaking optoelectronics. We also discuss the future opportunities and research directions in this field, such as developing advanced techniques to probe the emergent photonics and optoelectronics in an individual moir?? supercell; exploring new ferroelectric, magnetic, and multiferroic moir?? systems; and using external degrees of freedom to engineer moir?? properties for exciting physics and potential technological innovations.
