Electrically tuning exciton polaritons in a liquid crystal microcavity based on WS <sub>2</sub> monolayer
Abstract Two-dimensional (2D) transition-metal dichalcogenide (TMD) monolayers based on become a promising platform to study photonics and optoelectronics. Electrically controlling the excitonic properties of TMD monolayers can be realized in different devices. In this work, we realize the strong coupling between the excitons of WS 2 monolayers and a photonic cavity mode in a liquid crystal microcavity. The formed exciton polaritons can be electrically tuned by applying voltage to the microcavity. Our work offers a way to study exciton–polariton manipulation based on TMD monolayers by electrical methods at room temperature.
