## Description

- description: Semiconductor moire ́ systems, characterized by their periodic spatial
    light emission, unveil a new paradigm of active metasurfaces. Here, we show that
    ferroelectric moire ́ domains formed in a twisted hexagonal boron nitride (t-hBN)
    substrate can modulate light emission from an adjacent semiconductor MoSe2 monolayer,
    enhancing its functionality as an active metasurface. The electrostatic potential
    at the surface of the t-hBN substrate provides a simple way to confine excitons
    in the MoSe2 monolayer. The excitons confined within the domains and at the domain
    walls are spectrally separated due to a pronounced Stark shift. Moreover, the
    patterned light emission can be dynamically controlled by electrically gating
    the ferroelectric domains, introducing a novel functionality beyond conventional
    semiconductor moire ́ systems. Our findings chart an exciting pathway for integrating
    nanometer- scale moire ́ ferroelectric domains with various optically active functional
    layers, paving the way for advanced nanophotonic applications.
