Description
Carbon (C) allotropes have excellent physical properties for aerospace applications: 4-5× lighter than most metals, tensile strengths 100× larger than steel, high thermal conductivity, flexibility, wear resistance, and far superior mechanical-stress cycling capability when compared to metals. Transforming these materials into hightemperature superconductor wires could be of strong interest to employ in aerospace applications such as power system devices. Superconductivity can be induced by charge carrier (electron or hole) doping of base materials. We are studying the effect doping has on several C allotropes: amorphous thin films, graphite, carbon nanotubes, C fiber, and diamond-like-carbon films. Ion implantation of P, S, and O elements into the C host was done at a desired depth and calculated necessary dosing to represent a C:dopant ratio percentage. Resistivity measurements for temperatures ranging from 10 K to 300 K, Raman microscopy, SEM imaging, and PPMS characterization were employed. Results are here discussed and conclusions drawn regarding our future work.
