## Description

- description: "We present a dry pick-and-flip assembly technique for angle-resolved
    photoemission spectroscopy (ARPES) of van der Waals heterostructures. By combining
    Elvacite2552C acrylic resin and 1-ethyl-3-methylimidazolium ionic liquid, we prepared
    polymers with glass transition temperatures (Tg) ranging from 37 to 100 °C. The
    adhesion of the polymer to the 2D crystals was enhanced at \U0001D47B\U0001D420.
    By utilizing the difference in \U0001D47B\U0001D420, a 2D heterostructure can
    be transferred from a high-\U0001D47B\U0001D420 polymer to a lower-\U0001D47B\U0001D420
    polymer, which enables flipping its surface upside down. This process is suitable
    for assembling heterostructures for ARPES, where the top capping layer should
    be monolayer graphene. The laser-based micro-focused ARPES measurements of 5-layer
    WTe2, 3-layer MoTe2, 2-layer WTe2/few-layer Cr2Ge2Te6, and twisted double bilayer
    WTe2 demonstrate that this process can be utilized as a versatile sample fabrication
    method for investigating the energy spectra of 2D heterostructures."
