1. A method for generating one or more single crystal monolayers from two-dimensional van der Waals crystals, comprising:
providing a bulk material comprising a plurality of van der Waals crystal layers; and
exfoliating one or more single crystal monolayers of van der Waals crystal from the bulk material by applying a flexible and flat thermal release metal tape having a soluble protection layer and a metal layer to a surface of the bulk material;
wherein the flexible and flat metal thermal release tape has a surface root-mean-square roughness of less than 2 nm.
