Pinpoint pick-up and bubble-free assembly of 2D materials using PDMS/PMMA polymers with lens shapes
Pinpoint pick-up and bubble-free assembly of 2D materials using PDMS/PMMA polymers with lens shapes
The key to achieving high-quality van der Waals heterostructure devices made by stacking two-dimensional (2D) layered materials lies in having a clean interface without interfacial bubbles and wrinkles. In this study, the pinpoint pick-up and transfer system of 2D crystals is constructed using polymers with lens shapes. We report the …
