Fibonacci sequence of twist angles in superconducting multi-layer graphene and hydrogenated graphitic fibers
Nadina Gheorghiu, Charles R. Ebbing, George Y. Panasyuk +1
A range of twist angles between adjacent surfaces/volumes are intrinsic to natural graphite or artificially design in multi-layer graphene. In addition, stacking faults can be crea…
Magneto-structural phase transitions and two-dimensional spin waves in graphite
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
We have previously found experimental evidence for several quantum phenomena in oxygen-ion implanted of hydrogenated graphite: ferromagnetism, antiferromagnetism, paramagentism, tr…
Update on the method using nonlocal/noncontact differential conductance experimental data for direct probing Andreev reflections and for extracting the superconducting gap
Nadina Gheorghiu
In our previous work, high-temperature superconductivity (HTSC) was probed for the first time by using electrical differential conductance Gdiff(V) = dI/dV data as obtained from cu…
Boron Content and the Superconducting Critical Temperature of Carbon-Based Materials
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
In this paper, we present results on magnetization properties of boron nitride-carbon (BN-C) and boron carbide-carbon (B4C-C) granular mixtures. The temperature-dependent magnetiza…
Electric-field induced strange metal states and possible high-temperature superconductivity in hydrogenated graphitic fibers
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
In this work, we have studied the effects from increasing the strength of the applied electric field on the charge transport of hydrogenated graphitic fibers. Resistivity measureme…
Superconductivity in Hydrogenated Graphites
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
We report transport and magnetization measurements on graphitic materials that have been hydrogenated after being treated with octane. The temperature-dependent electrical resistiv…
