Summary: This study examines the properties of LiAlO2 thin films and compares them to Al2O3 and Li2O thin films for their potential use as ion-conducting dielectrics in metal-insulator-metal (MIM) capacitors. The reactive magnetron co-sputtering method is introduced for depositing LiAlO2, resulting in a smooth and uniform amorphous film with high transparency and a wide band gap. The incorporation of lithium ions into the alumina leads to enhanced conductivity and dielectric properties, making it a promising material for thin film capacitors with better energy storage performance and lower loss.

Summary: This manuscript presents a study on the structural characteristics, impedance spectroscopy, ac-conductivity, and dielectric loss of F-doped ZnO films grown by RF-magnetron sputtering at different temperatures. The results show that the electrical impedance spectroscopy can distinguish the contributions of grain and grain-boundary on the electronic properties. The ac-conductivity follows Jonscher power law, indicating hopping of charge carriers under ac electric field. The temperature-dependent dc-conductivity exhibits Arrhenius behavior. The dielectric loss is influenced by the doping level, with the low temperature grown samples showing higher conduction loss.

Summary: In this study, a-CNx thin films were deposited through RF magnetron sputtering with increasing nitrogen gas pressure to provide nitrogen radicals at high concentrations. The films' chemical bonding structures were evaluated using XPS, SXES, and NEXAFS, and compared with films deposited under uniform gas pressure. Increasing the gas pressure around the graphite target slightly increased the deposition rate and changed the chemical bonding structure of a-CNx films. However, the nitrogen content did not increase with the nitrogen gas pressure. The nitrogen incorporation in a-CNx films was more effective at higher RF powers, as indicated by SXES and NEXAFS spectra.

Summary: This study reports the material properties of gallium-doped zinc oxide grown from a high impulse magnetron sputtering system (HiPIMS) and compares them to those of radio frequency (RF) sputtering deposition. The results show that HiPIMS and RF processes yield similar outcomes under the same average power conditions. RF depositions exhibit slightly higher band gap and deposition rate, as well as lower resistivity and optical absorption coefficient. Both methods show that band gaps and grain size increase with deposition power.

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.
