Abstract

Thin bismuth strontium calcium copper oxide (BSCCO) films and BSCCO/insulator/BSCCO trilayers have been prepared on SrTiO₃ and MgO substrates by evaporation from elemental sources in ozone atmosphere. Accurate control of the stoichiometry is achieved through monitoring of the atomic fluxes by use of in situ atomic absorption spectroscopy, as well as by reflection high-energy electron diffraction. Nevertheless, nanometer-scale second- phase precipitates are sometimes observed. These defects and the flat regions around them have been probed by a variety of microanalytical techniques, including Rutherford backscattering spectroscopy, particle-induced x-ray emission, atomic force microscopy, microscopic secondary ion mass spectroscopy and transmission electron microscopy.
