Low Resistivity Contact to Iron-Pnicitide Superconductors

Superconductors are materials which carry electrical current without dissipation. However, feeding electrical current into a superconductor generates heat dissipation in the contacts and degrades maximum attainable current value. The degradation in contacts is also different depending on the different chemical nature of the superconducting materials.
