Conductor including nano-patterned substrate and method of manufacturing the conductor

A conductor comprising:

• a substrate;
• a nano pattern disposed on the substrate;
• and
• a two-dimensional (2D) material layer disposed over the nano pattern,
• wherein the substrate and the nano pattern comprise a same;
• and
• wherein the nano pattern and the substrate are an opaque body.

A method of manufacturing a conductor, the method comprising:

• depositing a mask layer over a substrate;
• removing a part of the mask layer thereby forming at least one opening in the mask layer, such that a remaining portion of the mask layer forms a nano pattern;
• etching a portion of the substrate through the at least one opening in the mask layer;
• removing the remaining portion of the mask layer;
• depositing a metal layer over the etched substrate;
• and
• forming a graphene layer over the substrate;
• wherein the metal layer comprises at least one of platinum (Pt), copper (Cu), silver (Ag), nickel (Ni), cobalt (Co), and gold (Au),
• wherein the metal layer is opaque.
