Claim:
1. A multilayer graphene composite structure, comprising: a first graphene sheet; a second graphene sheet spaced at least 5 nm away from the first graphene sheet; and a plurality of metallic spacers disposed between the respective first graphene sheet and the second graphene sheet; wherein each respective metallic spacer is in contact with the first graphene sheet and the second graphene sheet; wherein the plurality of metallic spacers are selected from the group including platinum particles, palladium particles, nickel particles, and combinations thereof; and wherein the respective graphene sheets each includes a plurality of etched defect structures, each etched defect structure positioned where each respective graphene sheet intersects a respective metallic spacer.
