Summary: The feasibility of large-scale surface modification of polyethylene terephthalate track-etched membranes (TM) using industrial roll-to-roll planar magnetron sputtering of Ti and TiO2 was investigated in this study. The results showed that the sputtered coatings did not significantly change water permeability or reduce pore diameter, indicating that magnetron sputtering is a viable method for the large-scale fabrication of hybrid membranes based on TM.

Summary: In this study, Zr-O-N films containing Ti were prepared by adding Ti ribbons on the racetrack of a Zr target during reactive magnetron sputtering. The addition of Ti ribbons prevented the target from being poisoned, especially at lower target currents, leading to a more controlled sputtering process. The color and electrical properties of the films were found to be closely related to the oxygen-to-metal ratio, while the N concentration did not have a significant impact.

Summary: High-throughput roll-to-roll processes are desirable for scaling up the production of flexible thermoelectric generators. Postdeposition in-line annealing processes have been explored to improve the functional performance of as-deposited films, with static vacuum oven treatment showing the most significant enhancement in film crystallinity and power factor. Infrared and electron-beam post treatments during in-line annealing also showed improvements in the power factor of bismuth telluride thin films.

Summary: This study fabricated Na-doped SnOx films and investigated the effect of Na dopant concentration on their crystal structure, electrical, and optical properties. The results showed that when Na+ substituted Sn2+, the hole concentration increased but the crystallite size reduced, leading to increased grain boundary and reduced carrier mobility. However, the electric resistivity still reduced due to the increase of carrier concentration. The Na-doped SnOx films exhibited an average optical transmission of approximately 65% in the visible range. The film sputtered from Sn + 3 at% Na alloy targets presented the best electrical property.

Summary: This study reports on the effects of aluminum and silicon segregation in mu m-thick magnetron co-deposited Si-Al films. It was found that an increase in aluminum content leads to the segregation of a separate crystalline phase, accompanied by the emergence of the c-Si phase. Silicon crystallization process is controlled by the redistribution of components in the film, which can be attributed to aluminum-induced crystallization process. The redistribution of aluminum and silicon phases in the amorphous matrix can be utilized to customize the electrophysical properties of the resulting coatings for applications in mm-band RF devices.

Summary: This study demonstrates that high deposition pressure can significantly impact the material properties of sputtered SiC thin films, altering the chemical bonding, composition, and opto-electrical properties. It shows that an increase in deposition pressure leads to a higher oxygen content and a change in the carbon phase, potentially meeting the application requirements for optoelectronic devices.

Summary: This study presents a method for fast deposition of metal oxynitride encapsulant layer on silver nanowires (AgNWs) to improve their electrical, thermal, and chemical stability. The encapsulant layers of AlOxNy, TiOxNy, and ZrOxNy demonstrate exceptional chemical, thermal, and electrical stability respectively. This method, which leverages reactive sputtering under moderate base pressures, is compatible with roll-to-roll processes and can be extended to various vacuum-compatible substrates and device architectures.

Summary: The ionization region model (IRM) was used to simulate a high power impulse magnetron sputtering discharge with a tungsten target. The study found that the initial peak in the discharge current was caused by argon ions bombarding the cathode target, after which W+ ions became the dominant ions and contributed to the total discharge current. Additionally, the findings were in good agreement with experimentally determined deposition rates.

Summary: This research investigates the structural and thermal stability of CrZrON coatings synthesized through reactive magnetron sputtering. The results show that the deposition temperature and oxygen ratio influence the structure and properties of the coatings. Coatings deposited at lower temperatures exhibit a columnar structure, while those deposited at higher temperatures show a transition towards a featureless or amorphous structure. The hardness of the coatings decreases with an increase in the oxygen ratio, primarily due to the formation of oxygen-rich compounds or oxides.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
