Abstract: A method of in-situ transfer during fabrication of a component comprising a 2-dimensional crystalline thin film on a substrate is disclosed. In one embodiment, the method includes forming a layered structure comprising a polymer, a 2-dimensional crystalline thin film, a metal catalyst, and a substrate. The metal catalyst, being a growth medium for the two-dimensional crystalline thin film, is etched and removed by infiltrating liquid to enable the in-situ transfer of the two-dimensional crystalline thin film directly onto the underlying substrate.

Abstract: A method for transferring graphene nondestructively and at a low cost. In the method, a graphene is used whose surface is coated with transferring media and whose original substrate is an electrode, the electrode is placed into an electrolyte, and the graphene is separated from the original substrate by means of the driving force of bubbles and the gas intercalation produced on the graphene electrode surface during electrolysis. Then, the graphene coated with transferring media is nondestructively combined with a target substrate. The transferring media is removed so as to transfer the graphene to the target substrate nondestructively. The transferring method results in no damage or loss with respect to the graphene and the original substrate, and the original substrate can be re-used. Furthermore, the method is easy to perform, works quickly, is easy to control, and is pollution-free.
