MgB2 tunnel junctions with native or thermal oxide barriers
R. K. Singh, R. Gandikota, J. Kim +2
MgB2 tunnel junctions (MgB2/barrier/MgB2) were fabricated using a native oxide grown on the bottom MgB2 film as the tunnel barrier. Such barriers therefore survive the deposition o…

Effect of damage by 2-MeV He ions and annealing on Hc2 in MgB2 thin films
R. Gandikota, R. K. Singh, J. Kim +9
The effect of damage induced by 2-MeV alpha particles, followed by annealing, on the critical temperature (Tc), resistivity, and upper critical field (Hc2), of three MgB2 films mad…

Effect of damage by 2-MeV He ions on the normal and superconducting properties of magnesium diboride
R. Gandikota, R. K. Singh, J. Kim +8
We have studied the effect of damage induced by 2-MeV alpha particles on the critical temperature, Tc, and resistivity of MgB2 thin films. This technique allows defects to be contr…
