Two dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as MoS2, WS2, MoSe2, and WSe2, have received extensive attention in the past decade due to their extraordinary physical properties. The unique properties make them become ideal materials for various electronic, photonic optoelectronic devices. However, performance is limited by relatively weak light-matter interactions atomically thin form factor. Resonant nanophotonic structures provide a viable way address this issue enhance 2D TMDCs. Here, we an overview of research area, showcasing relevant applications, including exotic light emission, absorption scattering features. We start overviewing concept excitons 1L-TMDC fundamental theory cavity-enhanced followed discussion on recent progress enhanced strong coupling valleytronics. nature enables broad range ways tune its electric optical Thus, continue reviewing advances TMDC-based tunable Next, survey over narrow bandwidths using 1L or few-layer TMDCs, applications photovoltaics photodetectors. also review efforts engineering scattering, e.g., inducing Fano resonances, wavefront TMDCs either integrating resonant structures, plasmonic/Mie metasurfaces, directly patterning monolayer/few layers then intriguing different types van der Waals heterostructures, Finally, draw our opinion potential opportunities challenges rapidly developing field research.

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

Correlated insulator of excitons in WSe ₂ /WS ₂ moiré superlattices

Science, Journal Year: 2023, Volume and Issue: 380(6647), P. 860 - 864

Published: May 11, 2023

A panoply of unconventional electronic states has been observed in moiré superlattices. Engineering similar bosonic phases remains, however, largely unexplored. We report the observation a correlated insulator tungsten diselenide/tungsten disulfide (WSe2/WS2) superlattices composed excitons, that is, tightly bound electron-hole pairs. develop pump probe spectroscopy method we use to observe an exciton incompressible state at filling νex = 1 and charge neutrality, indicating excitons. With varying density, continuously transitions into electron νe 1, suggesting mixed insulating between two limits. Our studies establish semiconducting as intriguing platform for engineering phases.
