## Description

- description: Integrating layered two-dimensional (2D) materials into 3D heterostructures
    offers opportunities for novel material functionalities and applications in electronics
    and photonics. We show that a simple UV-ozone pre-cleaning of the PDMS surface
    before exfoliation significantly reduces organic residues on transferred MoS2
    flakes. An additional 200 C vacuum anneal after transfer efficiently removes interfacial
    bubbles and wrinkles as well as accumulated strain, thereby restoring the surface
    morphology of transferred flakes to their native state. Our recipe is important
    for building clean heterostructures of 2D materials and increasing the reproducibility
    and reliability of 2D devices.
