Abstract
The present disclosure is directed towards systems and methods for transferring graphene from the surface of one substrate to another. In one particular embodiment, the graphene layer is grown on a surface of a first substrate, where the bottom of the first substrate is then affixed to the surface of a second substrate. The second substrate may include material made of a rigid or semi-rigid composition to provide structural support and backing to the first substrate. The graphene layer may then be delaminated from the first substrate and transferred to a target surface, such as the surface of an electronic device or biosensor.
Claims20
A method of transferring graphene comprising:
- growing a graphene layer on a surface of a growth substrate;
- affixing the growth substrate onto a surface of a transitory substrate;
- delaminating the graphene layer from the growth substrate;
- and
- transferring the graphene layer onto a target surface.
A system for transferring graphene comprising:
- a graphene wafer comprising:
- a growth substrate for growing a graphene layer;
- and
- a transitory substrate affixed to the growth substrate;
- a container filled with conductive solution;
- and
- an arm connected to a platform to immerse the platform in and out of the conductive solution.
The system of claim 19, where each score mark is located near an edge of the transitory substrate.
