Summary: Several studies have shown that rare earth elements can be used to regulate the magnetic anisotropy of garnet films. In this study, rare earth iron garnet (REIG) thin films were fabricated using pulsed laser deposition. The films exhibited different strain and crystal orientation depending on the ionic radius of the rare earth metal ions. The films also showed strong perpendicular magnetic anisotropy and different sensitivities to light at different wavelengths, which could be useful for high-density nano-scale magnetic information storage.

Summary: The incorporation of lithium in (111) NiO epitaxial layers grown using pulsed layer deposition technique on c-sapphire substrates has been studied. The effects of Li inclusion on the structural, morphological, electrical, and optical properties of the films were systematically investigated. It was observed that the concentration of Li in the film was higher at lower growth temperatures, but the crystalline quality decreased. There was a miscibility limit of Li in NiO, and Li clusters were detected in the films beyond a critical Li concentration. Li incorporation resulted in hydrostatic tensile strain in the NiO lattice, leading to a reduction in the bandgap and an improvement in the electrical conductivity of NiO layers. Ni-vacancy defects also played a significant role in controlling the conductivity of these samples.

Summary: Monolithic integration of metal oxide thin films with conventional semiconductors such as silicon and germanium allows for new functionalities in semiconductor devices. Using pulsed laser deposition (PLD), epitaxial strontium titanate (STO) films were grown on Ge (001) single crystal, achieving a sharp interface without interfacial amorphous oxide layer by optimizing surface preparation and deposition conditions. Factors such as Ge(001) surface substrate cleaning, growth temperature, oxygen partial pressure, and laser energy density are discussed for their effects on STO film growth, with the presence of O-2 leading to growth on (100) and (110) planes.

Summary: BaFe12O19 thin films with perpendicular magnetic anisotropy were deposited on GGG (111) substrates using pulsed laser deposition. The effects of annealing temperature on the microstructural, magnetic, and microwave properties of the films were investigated. The results showed that higher annealing temperatures led to better crystallization, higher perpendicular orientation, smoother surface morphology, and improved magnetic properties of the films. The films annealed at 1100°C exhibited a narrow ferromagnetic resonance linewidth and lower microwave loss.

Summary: In this paper, a high-performance self-driven ultraviolet photodetector (UV PD) with a vertical structure is presented. The UV PD shows outstanding performance including a low dark current, fast response speed, and excellent detectivity. The high performance is mainly attributed to the wider built-in electric field in the p-i-n junction and the vertical conductive structure with reduced dimensionality.

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: 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.
