Methods for manufacturing nonplanar graphite-based devices having multiple bandgaps

A method for forming a graphite-based device on a substrate, wherein the substrate comprises a plurality of zones, the method comprising:

• creating one or more non-planar graphene foundation layers in one or more selected zones in the plurality of zones;
• and
• concurrently generating one or more graphene stacks by using the one or more non-planar graphene foundation layers in the one or more selected zones, wherein a first graphene stack in the one or more graphene stacks comprises a first non-planar graphene layer that is characterized by (i) a first bending angle, (ii) a first curvature, (iii) a first characteristic dimension, (iv) a first graphene orientation, (v) a first graphene type, or (vi) a combination thereof.

A method for forming a graphite-based device on a substrate, wherein the substrate comprises a graphene foundation material and a plurality of zones, the method comprising:

• patterning the substrate to form one or more features in one or more selected zones in the plurality of zones, wherein a first feature in the one or more features is formed in a first zone in the one or more selected zones, and the first feature comprises (i) a non-planar surface, or (ii) at least two adjacent surfaces that are not on a common plane;
• and
• concurrently generating one or more graphene stacks in one or more selected zones in the plurality of zones, wherein a first graphene stack in the one or more graphene stacks comprises a first non-planar graphene layer (i) overlaying the non-planar surface of the first feature formed in the first zone or (ii) overlaying the at least two adjacent surfaces that are not on a common plane of the first feature formed in the first zone.
