- a layer of graphene
- the thin graphene layer
- graphene conducts electricity opens up avenues into some of the weirder areas of quantum physics
- a stack of graphene sheets
- this gives researchers the ability to etch graphene with unprecedented precision
- graphene stacks
- this level of control is important because the number of layers in a graphene stack determines its properties
- graphene stack
- such all graphene devices would help realize one of the ultimate goals in graphene based electronics
- researchers still have to show that their graphene sheets can be made to a consistently
