High Quality YBa2Cu3O7-x Superconducting Thin Films Grown by MOCVD

YBCO thin films have been grown by Metal Organic Chemical Vapour Deposition in ;I cold wall type reactor. The 0-diketonates of yttrium, barium and copper are used as precursors. Filrna have bcen deposited on (001 I MgO and (012) LaA103 single crystalline substrates. The morphology is very dependant on thc gas p h a x composition. Different oxygen partial pressures have been investigated. An inc...

Structural, Electrical and Optical Properties of Molybdenum Oxide Thin Films Prepared by Post-annealing of Mo Thin Films

Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...

Preparation and superconductivity of iron selenide thin films.

FeSe(x) (x = 0.80,0.84,0.88,0.92) thin films were prepared on SrTiO(3)(001)(STO), (La,Sr)(Al,Ta)O(3)(001) (LSAT), and LaAlO(3)(001) (LAO) substrates by a pulsed laser deposition method. All of the thin films show single-phase and c-axis oriented epitaxial growth, and are superconducting. Among them, the FeSe(0.88) thin films show a T(c,onset) of 11.8 K and a T(c,0) of 3.4 K. The upper critical ...
