## Description

- description: Recent studies have demonstrated that using h-BN as a substrate for
    the growth of transition metal dichalcogenides can significantly reduce excitonic
    linewidths. However, many other optical parameters still require optimization.
    In this work, we present a detailed study of the low-temperature photoluminescence
    efficiency of MBE-grown MoSe2 monolayers on h-BN substrates, comparing them to
    state-of-the-art exfoliated monolayers encapsulated in h-BN. We demonstrate that
    a quantitative comparison between samples requires accounting for interference
    effects and Purcell enhancement or suppression of the emission. By accounting
    for these effects in both photoluminescence and Raman signals, we show that the
    overall intrinsic luminescence efficiency is proportional to the sample coverage.
    Consequently, we find that exciton diffusion and edge effects are negligible in
    spectroscopy of MBE-grown samples, even for nanometer-sized crystals.
