“…Its origin is due to the solution−substrate interaction. 36,37 In conclusion, considering these results and the literature data, 30,35,38 these XRD results are consistent with the crystallization of YBCO through the chemical reaction I already proposed for fluorine-based MOD processes by several articles. 30 A similar study was then performed on the YBCO+ND system.…”

It was recently shown that the introduction of nanodiamond (ND) into a superconducting metal–organic deposited YBa2Cu3O7−δ (YBCO) film produces an increase in critical current density in self-field conditions (B = 0 T). Such improvement appears to be due to the formation of denser and smoother films than the samples deposited without ND. This paper presents the work done to understand the role of ND during YBCO nucleation and growth. A detailed study on YBCO+ND films quenched at different temperatures of the crystallization process was carried out. Results showed that the reaction responsible for YBCO production appeared effectively affected by ND. In particular, ND stabilizes one of the YBCO precursors, BaF2(1–x)O x , whose conversion into YBCO requires a prolonged time. Therefore, the YBCO nucleation is slowed down by ND and begins when the experimental conditions favor both thermodynamically and kinetically the formation of YBCO along the c-axis. This effect has important implications because the growth of a highly epitaxial c-axis YBCO film enables excellent superconducting performance.

“…Previous work already demonstrated the use of XPS depth profiling in the analysis of ZrO 2 added YBCO [5] and HfO 2 -added GdBa 2 Cu 3 O 7−δ [27] nanocomposite films. Recently, Santoni et al [28] showed that the Zr/Y ratio is a reliable parameter to evaluate zirconium distribution in YBCO matrix.…”

This work discusses the development of an analysis routine for evaluating the nanoparticle distribution in nanocomposite thin films. YBa2Cu3O7−δ (YBCO) nanocomposite films were synthesized via a chemical solution deposition approach starting from colloidal YBCO solutions with preformed nanoparticles. The distribution of the nanoparticles and interlayer diffusion are evaluated with X-ray photoelectron spectroscopy (XPS) depth profiling and compared with cross-sectional transmission electron microscopy (TEM) images. It is shown that the combination of both techniques deliver valuable information on the film properties as nanoparticle distribution, film thickness and interlayer diffusion.
