Abstract:
1. A method for depositing graphene, comprising: designating a plurality of site isolated regions (SIRs) on a surface of a substrate, depositing a first layer on one or more of the plurality of SIRs, wherein the first layer comprises non-conducting amorphous carbon; depositing a second layer on the first layer, wherein the second layer is a transition metal; annealing the substrate, the annealing resulting in converting a portion of the first layer disposed under the second layer to a third layer, wherein the third layer comprises conducting amorphous carbon; and removing a portion of the second layer from the surface of the substrate to expose the third layer; wherein the depositing, annealing, and removing a portion of layers on the plurality of SIRs are performed using processing parameters that are varied in a combinatorial manner.
