    for Strong Field Enhancement in TMD Monolayers

## Description

- description: "Enhancing light–matter coupling in two-dimensional (2D) semiconductors,
    such as transition metal dichalcogenide monolayers, remains a central challenge
    in nanophotonics due to their atomic thickness, which limits their interaction
    volume with light. Here, we demonstrate that higher-order optical resonances,
    including photonic guided modes (GMs) and quasi-bound states in the continuum
    (quasi-BICs) supported by a freestanding metasurface, provide exceptionally strong
    surface field enhancement, enabling efficient coupling with a tungsten disulfide
    (WS2) monolayer. Triangular-lattice polymer patterns on silicon nitride\r\nmembranes
    are fabricated to realize these higher-order modes. Simulations reveal that second-order
    modes possess optimal surface electric-field distributions that strongly overlap
    with the overlying WS2 monolayer, significantly outperforming their first-order
    counterparts. Photoluminescence (PL) measurements confirm a remarkable PL enhancement
    factor of 193 for the second-order GM, over an order of magnitude greater than
    that of the first-order modes. These results establish higher-order modes in freestanding
    metasurfaces as a promising route to engineer light–matter interactions in 2D
    semiconductors for advanced nanophotonic and quantum photonic applications."
