Summary: This work discusses the development of an analysis routine for evaluating the nanoparticle distribution in nanocomposite thin films. YBa2Cu3O7-delta (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.

Summary: The effects of chromium doping on magnetron sputtered and thermally annealed Ta3N5 thin films were investigated for the first time. Structural and compositional evolution of these films were closely studied using XRD, SEM, and SIMS. Despite the favorable ionic radius, poor chromium solubility in Ta3N5 was indicated, requiring further work to characterize Cr-Ta3N5 with desirable properties.

Summary: We present the photoabsorption response and resistive switching behavior of ion-implanted ZnO thin films. The role of oxygen vacancies in the evolution of these properties is studied using various techniques. The results suggest an improvement in the crystallinity of the films with ion fluence, and an enhancement in oxygen vacancy is responsible for higher photo response in the UV-Vis range. Engineering of bandgap also introduces enhanced absorption in visible regime. An asymmetric resistive switching behavior is observed in films implanted at the highest fluence, with a switching behavior from a high resistance state to a low resistance state under positive bias conditions and a rectifying nature under negative bias conditions. Oxygen vacancies play a crucial role in the modulation of photoabsorption response and resistive switching mechanism.

Summary: This work investigates the impact of annealing temperature on the structural and optical properties of ZnO films implanted with Ho+ and Nd+ ions. Highly oriented nanorods arrays of ZnO films were synthesized on silicon substrates using RF magnetron sputtering. Ion implantation enhanced the crystallinity of the films. The temperature-induced changes in lattice parameters and sizes of ZnO nanocrystals in nanorods were observed. Threshold temperatures for bulk crystallization and the photoluminescent properties of nanorods were identified. The study reveals that the implanted elements are distributed uniformly throughout the film thickness and accumulate at the SiOx/Si interface during high-temperature annealing.

Summary: The market for flexible, hybrid, and printed electronic systems is uncertain, but these systems are emerging daily, allowing for devices and systems that can be folded and stored in pockets. Cellulose-based modified nanopapers were developed as a physical support and gate dielectric layer for recyclable field-effect transistors (FETs). Impregnation of the nanopapers with sodium ions enabled low voltage FETs (<3 V), with high mobility (>10 cm2 V-1 s-1), current modulation (>105), and improved dynamic response. These transistors were successfully implemented into simple circuits such as inverters, showing clear discrimination between logic states. Besides improved electrical performance, these devices are a promising alternative for reliable, sustainable, and flexible electronics, even under stress conditions.

Summary: Due to the need to reduce global CO2 emissions, bio-based fuels are being explored. To reduce oxygen content, bio-oils need to be upgraded through catalytic hydrodeoxygenation (HDO) using bifunctional catalysts with metal and acid sites. Pt-Al2O3 and Ni-Al2O3 catalysts containing heteropolyacids (HPA) were prepared, and their properties were characterized. Ni-based catalysts showed higher conversion and selectivity to deoxygenated compounds, making them the most promising, despite suffering from deactivation over time.

Summary: The disordered microscopic structure of amorphous semiconductors leads to the formation of band tails in the density of states (DOS), which greatly affect charge transport properties. Kelvin Probe Force Microscopy (KPFM) is a powerful technique to measure the DOS, but lacks a model to interpret KPFM spectroscopy data on amorphous semiconductors of finite thickness. In this study, an analytical solution to the Poisson equation is provided for a metal-insulator-semiconductor junction interacting with the atomic force microscope tip, allowing for the fitting of experimental data and obtaining DOS parameters. This method was demonstrated on Indium-Gallium-Zinc Oxide (IGZO) thin-film transistors (IGZO-TFTs) and showed good agreement with values obtained from photocurrent spectroscopy.

Summary: There has been growing interest in using amorphous carbon thin films with low secondary electron yield (SEY) to reduce electron multipacting in particle accelerators and RF devices. Previous studies have shown that the SEY increases with the amount of hydrogen and is correlated with the Tauc gap. In this study, films produced by magnetron sputtering with varying amounts of hydrogen and deuterium were analyzed, and it was found that the maximal SEY decreases with the fraction of the graphitic phase in the films.

Summary: Neuromorphic computing is gaining popularity as a replacement for outdated technology in conventional computing systems. Artificial neural networks composed of memristor crossbars in hardware offer power, cost, and area-efficient in-memory computing and storage. Optoelectronic memristors (OEMs) can control resistive switching (RS) through both optical and electronic signals, solving crosstalk issues and providing a high-speed non-destructive method. This review summarizes recent advances in inorganic OEMs, analyzing the device structure and assessing their potential applications in logic gates, artificial neural networks, and artificial visual systems with consideration for their performance.

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.
