## Description

- description: 'Moiré heterostructures consisting of transition metal dichalcogenide
    (TMD) hetero- and homo bilayers have emerged as a promising material platform
    to study correlated electronic states. Optical signatures of strong correlations
    in the form of Mott–Wigner states and fractional Chern insulators have already
    been observed in TMD monolayers and their twisted bilayers. In this work, we use
    a moiré substrate containing a twisted hexagonal boron nitride (h-BN) interface
    to externally generate a superlattice potential for the TMD layer: the periodic
    structure of ferroelectric domains in h-BN effects a purely electrostatic potential
    for charge carriers. We find direct evidence for the induced moiré potential in
    the emergence of new excitonic resonances at integer fillings, and our observation
    of an enhancement of the trion binding energy by ≃ 3 meV. A theoretical model
    for exciton-electron interactions allows us to directly determine the moiré potential
    modulation of 30 ± 5 meV from the measured trion binding energy shift. We obtain
    direct evidence for charge order linked to electronic Mott–Wigner states at filling
    factors ν = 1/3 and ν = 2/3 through the associated exciton Umklapp resonances.'
