Microstructural Characterization of Covetic Materials

AMD Seminar

Abstract: A new class of nanocarbon-infused copper alloys, known as copper covetics (CuCv), exhibit enhanced electrical and thermal conductivities. We used advanced X-ray scattering and diffraction at the Advanced Photon Source, helium ion microscopy at the Center for Nanophase Materials Sciences, and high-resolution transmission electron microscopy and scanning transmission electron microscopy at the Center for Nanoscale Materials to study carbon nanostructures in CuCv and thin films. Our coordinated characterization results suggest that the carbon nanoparticles in CuCv comprise highly distorted graphenic carbon sheets, known as carbon nanoribbons, which are bonded to the copper matrix. These carbon nanoparticles, clusters, and carbon-rich networks in bulk CuCv and CuCv thin films are likely the origin of superior electrical and thermal properties in CuCv materials.
