Summary: The plasma-activated reactive evaporation technique was used to prepare indiumtin-oxide (ITO) films, and their optical and electrical properties were investigated. The results showed that the indium-to-tin mass ratio had a significant impact on the properties of ITO films, and appropriate ratios could achieve films with high transparency and low resistivity.

Summary: Transparent Conducting Oxides (TCOs) in the Epsilon-Near-Zero (ENZ) spectral region exhibit a large and ultrafast intensity-dependent refractive index, which is highly dependent on material properties and measurement conditions. This study demonstrates that extensive nonlinear optical measurements can be avoided by analyzing the material's linear optical response. By considering thickness-dependent material parameters, the impact on absorption and field intensity enhancement under different measurement conditions can be determined, allowing for optimization of the nonlinear response. Experimental measurements of Indium-Zirconium Oxide (IZrO) thin films with varying thicknesses confirm the agreement between experiment and theory, and show that film thickness and excitation angle can be adjusted simultaneously for optimizing the nonlinear optical response, enabling flexible design of highly nonlinear TCO-based optical devices.

Summary: Two types of parallel-plate capacitors, Cu/Si-oxide/Cu (MIM) and Cu/Si-oxide/indium-tin-oxide/Cu (MIM-ITO), were fabricated. The capacitance of MIM-ITO structure (1365.5 pF) was found to be twice as large as that of MIM structure (442 pF). The presence of ITO interlayer enhanced the 'edge effect' and led to the formation of non-stoichiometric Si2O3 phase in the Si-oxide film. The Si2O3 tetrahedrons exhibited strong spontaneous dipoles, resulting in additional net polarization in the Si-oxide film under an applied electric field. TEM images showed a (222)-preferred ITO crystalline phase at the Si-oxide/ITO interface, serving as the growth seed layer for Si2O3-containing Si-oxide film.

Summary: Tin-doped indium oxide (ITO) thin films were prepared at low substrate temperature using direct-current magnetron sputtering technology and applied as electrodes for silicon heterojunction solar cells (HJT). The chemical, electrical, and optical properties of ITO films deposited at different sputtering power were investigated. The optimized ITO films were used as electrodes for HJT solar cells, achieving a conversion efficiency of over 25.22%. Additionally, the degradation caused by ITO deposition was analyzed, and it was found that the degradation could be recovered through annealing. Furthermore, the degradation of solar cell efficiency in a dark nitrogen environment was monitored, revealing that the solar cells with the highest average conversion efficiency showed poor stability, primarily due to the degradation of the fill factor.

Summary: This numerical study investigates the linear optical response of a plasmonic dipole antenna array in combination with an epsilon-near-zero (ENZ) thin film. It shows that the antenna array properties can be strongly or weakly influenced by the coupling with the ENZ film, and the presence of low-loss ENZ films can make the lower polariton branch visible. Additionally, thick, lossy ENZ films may result in the lower polariton branch being unobservable.

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.

The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

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: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

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.
