The (a,b)-plane infrared and visible conductivity (30–30000 cm−1) of a 40% praseodymium-substituting yttrium YBa2Cu3O7 film displays a loss of spectral weight over two separate energy ranges when lowering the temperature. A first loss of spectral

A method for determining both the thickness and the average stoichiometry of thin films is presented. The method is based on implanting radioactive -sources in the substrate prior to layer growth and measuring the energy loss of the -particles as the

We describe a novel method by which normal metal/insulator/high- T c planar tunnel junctions can be obtained. In this method the thin dielectric layer is produced by the in-situ oxidation of a metal with a strong electronegativity, through diffusion

We studied the influence of substrate defects on the morphological and transport properties of Y1Ba2Cu3O7−x high Tc superconducting thin films. The substrate defects were characterized by dispersive and nondispersive cathodoluminescence in the scan

We used cathodoluminescence (CL) in the Scanning Electron Microscope (SEM) for studying different superconducting properties. CL measurements were used to reveal and identify non-superconducting phases which existed in the Y1Ba2Cu3O6+X (YBCO) high Tc

We report the measurement and analysis of the resistive transitions under applied magnetic fields for c axis oriented thin films of Y0.6Pr0.4Ba2Cu3O7 (PYBCO). We estimate the in-plane and out-of-plane coherence lengths to be much larger YBCO. Our dat

We report here the results of a comparative investigation of the perfection of epilayers of high temperature superconducting (HTS) YBa2Cu3O7−x (YBCO) films deposited by pulsed laser deposition (PLD) and organometallic chemical vapor deposition (OMC

We report the fabrication and operation of YBCO thin film DC SQUIDs on Sapphire substrates. The film are prepared by the sequential deposition of Cu, Y2O3, BaF2, with post annealing, and are about 1μm thick. The film are patterned by a conventional

Cathodoluminescence (CL) of thin films of high Tc superconductors was studied in the scanning electron microscope. The depth and the lateral locations of the different phases can be revealed. In thin films, unlike the bulk superconductors, the CL inf
