Superconductivity of Magnesium Diboride: Theoretical Aspects

Effects of carbon doping on superconductivity in magnesium diboride

We introduce carbon onto boron sites in MgB2 . The resulting changes in crystal lattice constants and superconducting transition temperature Tc are characterized by x-ray-diffraction, magnetic susceptibility, and electrical resistance measurements. The consequence of approximately 10% carbon doping of boron sites is a 1% contraction of the intraplane lattice dimension ~with no appreciable chang...

Group and developing high − T C Superconducting Nanowire Single Photon Detectors for deep space communication. He has been a Fulbright Scholar and received national and international fellowships & awards for this study. During his Ph.D. studies, he has worked on Superconducting Quantum Interference Device Chains and demonstrated the existence of localized quantum phase-slips which are crucial f...

Zr Stabilized Ti5Te4-Type Hafnium Telluride

Hafnium and zirconium are commonly thought to be very similar in chemistry. However, they are surprisingly dissimilar in the chemistry of metal-rich chalcogenides. For instance, Hf2S [1] and Hf2Se [2] are comprised of hexagonal closepacked double metal atom layers spaced by sulfur or selenium while both Zr2S [3] and Zr2Se [4] crystallize in a Ta2P-type structure [5]. Zr2Te [6] and Hf2Te [7] ado...

Correlation-induced superconductivity dynamically stabilized and enhanced by laser irradiation

Studies on out-of-equilibrium dynamics have paved a way to realize a new state of matter. Superconductor-like properties above room temperatures recently suggested to be in copper oxides achieved by selectively exciting vibrational phonon modes by laser have inspired studies on an alternative and general strategy to be pursued for high-temperature superconductivity. We show that the superconduc...
