✦ Synopsis

We have grown Bal _~K.~BiO3/BaBi2Oy/Bal _xKxBiO3 trilayers by molecular beam epitaxy. Junctions made from these trilayers exhibit transport ranging from hopping conduction to superconductor-insulator-normal metal tunneling and possibly to superconductor-insulator-superconductor Josephson tunneling. Critical currents have been measured for junctions grown on (110) NdGaO3 substrates.
