Definition
Epitaxial graphene is an electronic material, made of at least one layer of graphene (each one one atom thick), epitaxially grown on a suitable substrate. The properties of the material depend on the substrate on which it is grown.

The particular arrangement of the graphene layers, what is called the type of stacking, greatly affects the electronic properties of the material. In graphite, each graphene layer is arranged such that half of the atoms lie directly over the center of a hexagon in the lower graphene sheet, and half of the atoms lie over an atom. This is the so-called Bernal stacking.
