## Description

- description: Interlayer excitons in semiconducting bilayers separated by insulating
    hBN layers constitute a promising platform for investigation of strongly correlated
    bosonic phases. Here, we report an optical method for the generation and characterization
    of long-lived interlayer excitons. We find confirmation of tightly bound interlayer
    excitons by measuring 1s and 2s intralayer excitons in each layer concurrently.
    Using a pump-probe technique, we find interlayer exciton lifetimes up to 8.8 µs,
    increasing with the thickness of the hBN. Optical access to long-lived interlayer
    exciton dynamics is promising for exploring degenerate Bose-Fermi mixtures composed
    of interlayer excitons and itinerant electrons or holes.
