  Integrating monolayers of two-dimensional semiconductors in planar, and
potentially microstructured microcavities is challenging because of the few,
available approaches to overgrow the monolayers without damaging them. Some
strategies have been developed, but they either rely on complicated
experimental settings, expensive technologies or compromise the available
quality factors. As a result, high quality Fabry-Perot microcavities are not
widely available to the community focusing on light-matter coupling with
atomically thin materials. Here, we provide details on a recently developed
technique to micro-mechanically assemble Fabry-Perot Microcavities. Our
approach does not rely on difficult or expensive technologies, and yields
device characteristics marking the state of the art in cavities with integrated
atomically thin semiconductors.
