Claim Text:
1. A method of forming graphene on a synthetic diamond substrate, comprising: providing a synthetic diamond substrate selected from the group consisting of single crystal diamond, ultrananocrystal diamond, and nanocrystal diamond; defining a graphitization pattern on the synthetic diamond substrate prior to ion bombardment using photolithography; treating a portion of the synthetic diamond substrate by ion bombardment, the ion bombardment damaging sp heating the synthetic diamond substrate at an annealing temperature for about two minutes to about ten minutes to permit annealing to occur in the treated portion of the synthetic diamond substrate, wherein the annealing temperature is from about 600° C. to about 900° C. whereby the treated portion of the synthetic diamond substrate is transformed into one or more graphene layers; and reducing the one or more of graphene layers to ten or less graphene layers if the number of graphene layers formed exceeds ten.
