The ions can be Si, C, or other ions such as Au. The annealing can be carried out using a thermal source of heating or by irradiation with at least one laser beam or other high energy beam.

  • Patent number: 8926853
    Abstract: Aspects of the invention are directed to a method of forming graphene structures. Initially, a cluster of particles is received. The cluster of particles comprises a plurality of particles with each particle in the plurality of particles contacting one or more other particles in the plurality of particles. Subsequently, one or more layers are deposited on the cluster of particles with the one or more layers comprising graphene. The plurality of particles are then etched away without substantially etching the deposited one or more layers. Lastly, the remaining one or more layers are dried. The resultant graphene structures are particularly resistant to the negative effects of aggregation and compaction.
