A lint roller for superclean graphene

Nanowerk.com - 26 сентября, 2019 - 12:26
Researchers demonstrate that the amorphous carbon contaminants on CVD-produced graphene, which could greatly degrade its properties, can be removed by an activated carbon-coated lint roller, relying on the strong interactions between the amorphous carbon and activated carbon. Large-area graphene surfaces treated with this lint roller exhibit a high cleanliness of 99% with a low degree of polymer residue after transfer onto a functional substrate. This superclean graphene has extremely low contact resistance and ultrahigh carrier mobility.
