Carbon doping of superconducting magnesium diboride

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...

Superconducting Properties of Graphene Doped Magnesium Diboride

Characterization of Superconducting Magnesium-Diboride Films on Glassy Carbon and Sapphire Substrates

IBA methods were applied to measure elemental depth profiles of precursors and superconducting MgB2 thin films deposited on glassy carbon (Good Fellows) and sapphire (Al2O3) substrates. For each type of substrates we obtained a pair of samples i.e. one amorphous precursor and one superconducting film which were then characterized. A He beam was used to bombard both, precursors and superconducti...
