Abstract

Thin films of the intermetallic compounds AuAl2 and AuIn2 were prepared and used as electrodes in AuAl2/oxide/Al,Al/oxide/AuIn2, or AuAl2/oxide/AuIn2 tunnel junctions. The tunnel barriers were produced by rf sputter oxidation. The temperature dependence of the energy gaps of the AuAl2 and AuIn2 films was measured and found to agree well with BCS theory.
