Summary: The effects of A-site transition from Ca2+ to Cd2+ on the microstructure, morphology, and electrical properties of Ca(1-x)CdxCu(3)Ti(4)O(12) thin films were investigated. The films exhibited smooth and compact surfaces without cracks. The transition from Ca2+ to Cd2+ resulted in changes in grain size and electrical properties. In particular, the simultaneous occupancy of A sites by Ca2+ and Cd2+ improved the dielectric and nonlinear properties of Ca1-xCdxCu3Ti4O12 films.

Summary: Epitaxial thin films of 0.67[Pb(Mg1/3Nb2/3)O-3]-0.33[PbTiO3] (PMN-33PT) were prepared using ceramic targets and pulsed-laser deposition (PLD), enriched with PbO (and MgO). The composition and crystal structure were analyzed using high-resolution X-ray diffraction. Chemical analysis of the films revealed deviations from stoichiometry, especially in Pb and Mg content. Custom-made ceramic targets were found to effectively tune the film stoichiometry, showcasing their advantage over single-crystal targets in PLD growth of complex metal oxides. The sample with the largest deviations from nominal stoichiometry, prepared from a target with 20 mol% PbO excess, exhibited the highest longitudinal piezoelectric coefficient.

Summary: Cadmium oxide (CdO) thin films were successfully deposited on glass substrates by the sol-gel spin coating method. The effects of the annealing temperature and Zirconium (Zr) doping on the physical properties of the CdO thin films were investigated. It was found that 550 °C is the optimal annealing temperature with a good crystallinity for the CdO thin films. Then, by using this temperature, different Zr doping concentrations (0, 1, 3, 5 and 7%) were prepared at the same experimental conditions. The X-ray diffraction (XRD) patterns of all the as-prepared thin films showed a polycrystalline nature with a face centered cubic (FCC) structure and that Zr incorporated the sites of Cadmium (Cd) up to 3% concentration, while the excess Zr doping (x > 3%) aggregated at the grain boundaries of the CdO lattice. Scanning electron microscopy (SEM) analysis revealed homogeneous and dense grains distribution with a film thickness of 30 μm. The optical study showed an increase in optical transmittance of CdO with Zr doping up to 3% and then a decrease onwards within the same wavelength region. The optical band gap values increased from 2.41 to 2.67 eV with increasing Zr doping which was explained by the Burstein-Moss effect. The minimum electrical resistivity (5.32 x 10(-1) Ω·cm) was obtained for the film coated with 3% Zr using the four-probe method.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
