## Description

- description: Excitons, quasiparticles formed by the binding of an electron and a
    hole through electrostatic attraction, hold promise in the fields of quantum light
    confine- ment and optoelectronic sensing. Atomically thin transition metal dichalco-
    genides (TMDs) provide a highly versatile platform for hosting and manipu- lating
    excitons, given their robust Coulomb interactions and exceptional sen- sitivity
    to dielectric environments. In this study, we present a photoelectrical sensing
    technique, termed optically coupled microwave impedance microscopy (OC-MIM). OC-MIM
    enables the sensitive probing of exciton polarons and their Rydberg states at
    the nanoscale, unveiling their potential as localized quantum sensors. By utilizing
    this technique, we explore the interplay between excitons and material properties
    at the nanoscale, including carrier density, in- plane electric field, and dielectric
    screening. Furthermore, we employ a neural network algorithm to enable automated
    data analysis and quantitative extrac- tion of nanoscale electrical information.
    Our findings establish an invaluable sensing platform and readout mechanism, enhancing
    the understanding of ex- citon excitations and their applications in the quantum
    realm.
