Abstract

MgB ₂ tunnel junctions (MgB ₂/barrier/MgB ₂) were fabricated using a native oxide grown on the bottom MgB ₂ film as the tunnel barrier. Such barriers therefore survive the deposition of the second electrode at 300°C, even over junction areas of ∼1 mm ². Studies of such junctions and those of the type MgB ₂/native or thermal oxide/metal (Pb, Au, or Ag) show that tunnel barriers grown on MgB ² exhibit a wide range of barrier heights and widths.
