This paper addresses the synthesis and a detailed electrical analysis of individual copper nanowires (CuNWs). One dimensional CuNWs are chemically grown using bromide ions (Br-) as a co-capping agent. By partially replacing alkyl amines with Br-, the isotropic growth on Cu seeds was suppressed during the synthesis. To study the electrical properties of individual CuNWs, a fabrication method is developed which does not require any e-beam lithography process. Chemically grown CuNWs have an ampacity of about 30 million amps per cm2, which is more than one order of magnitude larger than bulk Cu. These good quality, easy to synthesize CuNWs are excellent candidates for creating high ampacity wires and flexible printable electronics.
