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…
Strong Fiber from Uniaxial Fullerene Supramolecules Aligned with Carbon Nanotubes
John Bulmer, Michelle Durán-Chaves, Daniel M. Long +10
Carbon nanotube (CNT) wires approach copper's specific conductivity and surpass carbon fiber's strength, with further improvement anticipated with greater aspect ratios and incorpo…
Flat-band energy analysis of the temperature-dependent superconducting gap for hydrogenated graphite fibers found from nonlocal electrical conductance experimental data
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
Experimental evidence of novel phenomena in hydrogenated graphite fibers is found. An indirect excitonic mechanism is likely leading to a SC state below the temperature Tc = 50 K,…
Magnetism and Superconductivity in Hydrogenated Graphite Foils
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
Unique to certain unconventional superconductors is the coexistence of magnetism and superconductivity. We have previously found ferromagnetism and superconductivity in hydrogenate…
Quantum spin Hall effect in two-dimensional metals without spin-orbit coupling
Aiying Zhao, Qiang Gu, Timothy J. Haugan +2
The quantum spin Hall effect has been observed in topological insulators using spin-orbit coupling as the probe, but it has not yet been observed in a metal. An experiment is propo…
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…
The Zeeman, Spin-Orbit, and Quantum Spin-Hall Interactions in Anisotropic and Low-Dimensional Conductors
Aiying Zhao, Qiang Gu, Timothy J. Haugan +1
When an electron or hole is in a conduction band of a crystal, it can be very different from 2, depending upon the crystalline anisotropy and the direction of the applied magnetic…
Spacing Dependent and Doping Independent Superconductivity in Intercalated 1T Two Dimensional SnSe2
Hanlin Wu, Sheng Li, Michael Susner +4
The weak van der Waals interlayer interactions in the transition metal dichalcogenide (TMD) materials have created a rich platform to study their exotic electronic properties throu…
Prediction of Antiferromagnetism in Barium Chromium Phosphide Confirmed after Synthesis
R. A. Jishi, J. P. Rodriguez, T. J. Haugan +1
We have carried out density-functional theory (DFT) calculations for the chromium pnictide BaCr2P2, which is structurally analogous to BaFe2As2, a parent compound for iron-pnictide…
