Molecular-Beam Epitaxially Grown MgB₂ Thin Films and Superconducting Tunnel Junctions

(From [22]): Schematic of the hybrid physical-chemical vapor deposition technique for growing epitaxial MgB₂ films. Vaporized Mg reacts with B from the flowing diborane gas, and an MgB₂ film condenses onto the substrate. ^©Nature publishing group.
