Abstract Scope We prepared nanophase carbon infused copper alloys by electron-beam melting. This new class of materials, known as covetics, exhibit enhanced electrical and thermal conductivities. Up to ≈30% enhancement in electrical conductivity was observed in covetic copper thin films deposited by electron-beam evaporation. Our results revealed remarkable promise for use in energy saving applications. Understanding the nature of interaction between the carbon nanostructures and their host metal is critical to elucidate the origins for superior properties. We utilized helium ion microscopy (HIM), high-resolution transmission electron microscopy (HRTEM) and scanning transmission electron microscopy (STEM) in the study of carbon nanostructures in copper covetics and thin films. HIM provided unique opportunity to visualize carbon nanostructures in metal matrix due to its superior contrast and resolution; HRTEM and STEM elemental mapping verified the existence of carbon nanoparticles, clusters, and networks in the host copper. Details of experimental results will be presented in this talk.
