Abstract
Graphene layers and associated methods are disclosed. In one aspect, for example, a method of making graphene on a diamond substrate is provided. Such a method can include applying a layer of a metal to a crystallographic face of the diamond substrate, and heating the diamond substrate under vacuum to convert a portion of the diamond substrate at the crystallographic face into graphene. In another aspect, the layer of metal is applied only on diamond substrate faces having a same crystallographic orientation. In yet another aspect, the layer of metal is applied to only a single crystallographic face of the diamond substrate. Additionally, in one aspect, converting the portion of the diamond substrate at the crystallographic face into graphene includes converting the portion of the diamond substrate by a martensitic transformation.
