Process flow for vdW heterostructure fabrication. Schematic of the dry-polymer-transfer process used to fully encapsulate a 2D flake with hBN (here, it is graphene).577 This process relies only on the vdW interactions between hBN and other 2D flakes and can be used to pick up and transfer a number of different 2D materials.
