## Description

- description: Moiré superlattices of transitional-metal dichalcogenides exhibit strong
    electron–electron interaction that has led to experimental observations of Mott
    insulators and generalized Wigner crystals. In this Letter, we report direct measurements
    of the thermodynamic gaps of these correlated insulating states in a dual-gate
    WS2/WSe2 moiré bilayer. We employ microwave impedance microscopy to probe the
    electronic features in both the graphene top gate and the moiré bilayer, from
    which we extract the doping dependence of the chemical potential of the moiré
    bilayer and the energy gaps for various correlated insulating states utilizing
    the Landau quantization of graphene. These energy gaps vary across different locations
    on the samples but are relatively insensitive to the application of an external
    electric field or magnetic field to the WS2/WSe2 moiré bilayer.
