3D graphene refers to a material that ... carbon atoms arranged in a hexagonal pattern. When multiple layers of graphene are stacked on top of each other, the resulting material is known as graphite, ...

Schematic of a lithium-ion battery. The graphite layers in the anode help store charge by intercalating lithium ions between individual graphene layers. Credit: OpenStax, CC By 4.0 While all these ...

The material goes from being a 3D electron system to a 0D one ... Another big surprise is that this QHE is very sensitive to even/odd number of graphene layers. The electrons in graphite are similar ...
