Fabrication and electrical transport properties of epitaxial Nd1.85Ce0.15CuO4−y films

Epitaxial Growth and Properties of Doped Transition Metal and Complex Oxide Films

“…MS has been used to grow a variety of epitaxial oxides of interest as optical waveguides, [217] light emitters, [218][219][220][221] capacitor dielectrics, [222,223] high-T c superconductors, [224][225][226][227][228] photocatalysts, [229] gas sensors, [83] ferroelectrics, [230][231][232][233] piezoelectrics, [46,234] conductive oxides, [235][236][237][238][239] gate dielectrics, [29,[240][241][242][243][244] magnetoresistive materials, [245][246][247][248][249][250][251][252][253][254][255][256][257] general purpose insulators, [258,259] magnetic insulators, [260,261...…”

Thermal treatments and evolution of bulk Nd1.85Ce0.15CuO4 morphology

“…For this reason, a special attention has been devoted in the last years to the development of reliable experimental procedures allowing to efficiently control the cerium doping level and the subsequent oxygen reduction process in argon or nitrogen atmosphere. The definition of optimal conditions of growth and thermal annealing is still under [13]. The study presented here is specifically focused on this issue and its main motivation resides in the search for a reliable way of producing bulk samples from which high quality thin films could be successfully realized.…”

At the interface between electron and hole-doped cuprates

“…Initial experiments have shown that YBCO and NCCO can be combined on a single chip and that, by either oxygen or vacuum annealing, superconductivity can be switched between the two layers [53]. A specific annealing procedure tailored to the oxygenation requirements of YBCO and the reduction requirements for NCCO allows both layers to become superconducting [56]. Other experiments employed N 2 O as a deposition gas for pulsed laser deposition (PLD) instead of O 2 for NCCO [54,58].…”

“…There are several reports on the combination of electron and hole-doped cuprates in literature, most of which focus on the combination of hole-doped YBa 2 Cu 3 O 7-x (YBCO) with electron-doped NCCO [53][54][55][56][57]. Initial experiments have shown that YBCO and NCCO can be combined on a single chip and that, by either oxygen or vacuum annealing, superconductivity can be switched between the two layers [53].…”

“…Combinations of electron and hole-doped cuprates have previously been studied in the YBCO/NCCO system in various configurations [53][54][55][56][57]. Other than the appearance of a Josephson effect, none of the above described effects have been observed [55].…”
