Abstract
A method for forming a graphite-based device on a substrate having a plurality of zones is provided where the substrate is carbon doped in zones. Each such zone comprises a plurality of dopant profiles. One or more graphene stacks are generated in the doped zones. A graphene stack so generated comprises a non-planar graphene layer characterized by a bending angle, curvature, characteristic dimension, graphene orientation, graphene type, or combinations thereof. A method for forming a graphite-based device on a substrate is provided, the substrate comprising a graphene foundation material and a plurality of zones. The substrate is patterned to form features in the zones. One feature comprises a non-planar surface or at least two adjacent surfaces that are not coplanar. One or more graphene stacks are concurrently generated, at least one of which comprises a non-planar graphene layer overlaying the non-planar surface or the at least two adjacent surfaces.
