Hey.

How to maintain the Casimir effect when you place metal plates are used sheet of graphene.

Thank you.
Goodbye.

A single sheet of graphene is rather floppy, which would make it hard to measure the Casimir effect between two sheets of graphene.

I suggest that you use multi-layer sheet of graphene to make the plate stiff.
Or mount the graphene on a very flat surface (eg optical glass, or a silicon wafer).
Or just use metal plates?
