Claim:
1. A method of forming a graphite-based structure on a substrate comprising: (A) patterning the substrate thereby forming a plurality of elements on the substrate, each respective element in the plurality of elements separated from an adjacent element on the substrate by a corresponding trench in a plurality of trenches on the substrate, wherein (i) each respective element in the plurality of elements has a corresponding top surface, (ii) each respective trench in the plurality of trenches is characterized by a trench surface, (iii) each respective trench in the plurality of trenches separates a pair of adjacent elements in the plurality of elements, (iv) each top surface of each respective element in the plurality of elements is separated from an adjacent trench surface by a side wall of the respective element, (v) a top surface of a first element in the plurality of elements is characterized by a first elevation, (vi) a trench surface of a first trench in the plurality of trenches, the first trench separating the first element from another element in the plurality of elements, is characterized by a second elevation, (vii) the first elevation is other than the second elevation, and (viii) a first orthogonal projection of the top surface of the first element and a second orthogonal projection of the trench surface of the first trench onto a common plane are contiguous or overlapping; and (B) segmentedly depositing a graphene initiating layer onto the top surface of each respective element in the plurality of elements at an energy level that restricts deposition of the graphene initiating layer to the top surface of each respective element; and (C) generating graphene using the graphene initiating layer thereby forming the graphite-based structure.
