“…The PLD method offers flexibility in the growth of thin films, including the size of nanoparticles, composition, and phase, by controlling the laser excitation source (wavelength), substrate temperature, oxygen partial pressure, and target composition [12,13]. The PLD techniques have been successfully applied to prepare different oxide materials, such as superconductors [14][15][16][17][18], magnetic materials [19,20], perovskite cathodes, and barrier layers for solid oxide fuel cells [21][22][23][24][25], including perovskite thin-film solar cells [26,27]. In particular, the preparation of nanostructure thin films, such as Au-TiO 2 [28,29], and nanostructure multilayered perovskite cathodes [30] under different PLD growth conditions were explored.…”

Iron oxide nanostructures were synthesized using the carbothermal reaction of Fe microspheres generated by infrared pulsed laser ablation. The Fe microspheres were successfully deposited on Si(100) substrates by laser ablation of the Fe metal target using Nd:YAG pulsed laser operating at λ = 1064 nm. By varying the deposition time (number of pulses), Fe microspheres can be prepared with sizes ranging from 400 nm to 10 µm. Carbothermal reaction of these microspheres at high temperatures results in the self-assembly of iron oxide nanostructures, which grow radially outward from the Fe surface. Nanoflakes appear to grow on small Fe microspheres, whereas nanowires with lengths up to 4.0 μm formed on the large Fe microspheres. Composition analyses indicate that the Fe microspheres were covered with an Fe3O4 thin layer, which converted into Fe2O3 nanowires under carbothermal reactions. The apparent radial or outward growth of Fe2O3 nanowires was attributed to the compressive stresses generated across the Fe/Fe3O4/Fe2O3 interfaces during the carbothermal heat treatment, which provides the chemical driving force for Fe diffusion. Based on these results, plausible thermodynamic and kinetic considerations of the driving force for the growth of Fe2O3 nanostructures were discussed.

“…Other studies which used Gd, Nd and dilute rare-earth doping are shown to repair grain boundaries or improve flux pinning that enhanced superconducting properties [10][11][12][13]. Addition of particle and nanoparticles such as Ag, Dy, Zr, Eu, Nb, Al and Ca-iridates improves grain connectivity [14][15][16][17][18][19][20][21].…”

Effect of In2O3 on the grain connectivity and superconducting behavior of Bi2Sr2−xInxCaCu2O8+d

The effect of In 2 O 3 on grain connectivity and superconducting properties of Bi-2212 was investigated. Indium was intentionally doped on the Sr-site of BSCCO at doping levels from x = 0 to x = 0.8. Accessing the Sr lattice site in BSCCO provides useful control on the possible effect of indium on its superconducting behavior and microstructural properties. Results show that the superconductivity persists in BSCCO even at high indium concentration (x = 0.8). However, secondary phases form at x ≥ 0.4 indium concentration affecting normal resistivity, magnetic susceptibility response and superconducting transition temperature of BSCCO. Formation of secondary phases weakens the diamagnetic intergrain coupling. An apparent increase in the formation of micron-sized grains is related to the increased sinterability of BSCCO with indium doping. The enhanced sinterability of BSCCO with indium provides possibility of synthesizing thin films with reduced thermal heat treatment.
