Abstract
A method of manufacturing an electrical conductor includes providing a substrate layer, depositing a surface layer on the substrate layer that has pores at least partially exposing the substrate layer, and forming graphene deposits in the pores. Optionally, the graphene deposits may be formed only in the pores. The graphene deposits may be formed along the exposed portions of the substrate layer. The graphene layers may be selectively deposited or may be deposited to cover an entire layer. Optionally, the forming of the graphene deposits may include processing the electrical conductor using a chemical vapor deposition process using an organic compound precursor and heat of sufficient temperature to facilitate graphene growth on the metal compound comprising the substrate layer.
