Summary: Ultrathin carbon nanoribbons exhibiting metallic electrical conductivity synthesized without chemical doping. By engineering precise atomic-scale edge configurations and width parameters during bottom-up chemical vapor deposition growth, the carbon ribbons achieve ballistic electron transport at room temperature. Scattering losses common in conventional carbon nanomaterials eliminated. Scalable semiconductor ultra-dense interconnect/ ballistic nanoelectronic circuit fabrication.
