Summary: In this study, CZTS thin films were deposited on SLG/Mo substrates using pulsed laser deposition (PLD) technique, with the optimal substrate temperature found to be 400 degrees C for achieving the desired properties for PV application. Increasing the substrate temperature led to an increase in zinc content and a decrease in optical energy band gap of the films. Post-annealing of the films further improved crystallinity and led to the formation of a ZnS secondary phase, resulting in a photoconversion efficiency of 3.3% in photovoltaic devices.

Summary: In this study, we investigated the effect of laser repetition rate on the properties of FST superconducting films deposited by pulsed laser deposition. We found that as the laser repetition rate increases, the crystallinity and stoichiometry of the films deteriorate, resulting in a degeneration in superconductivity. However, by increasing the substrate temperature, we were able to successfully deposit high-performance FST films at a high repetition rate.

Summary: Samarium doped ceria thin films were successfully deposited on Si (100) substrates at 500 and 600 degrees C using Pulsed Laser Deposition. X-ray Diffraction confirmed the presence of Samarium Doped Cerium Oxide crystalline compound in the films. Atomic Force Microscopy and Scanning Electron Microscopy revealed high quality films with low roughness, especially for the sample deposited at 600 degrees C. X-ray Photoelectron Spectroscopy showed an increased proportion of Ce3+ in the deposited films compared to the target. Spectroscopic Ellipsometry analysis calculated a refractive index under 2.2 in the visible and near-infrared domain. Nanoindentation tribometric measurements indicated a decrease in elasticity modulus and hardness with increasing substrate temperature. These films show potential as electrolyte materials for new generation electrochemical devices.

Summary: In this study, beta-tricalcium phosphate (β-TCP)/ZrO2 composite films were prepared using pulsed laser deposition technology, and the effects of different laser fluences on the properties of the films were investigated. The results showed that increasing the laser fluence resulted in an increase in the number of particles and droplets on the film surface, as well as an improvement in crystallinity. Properly increasing the laser fluence can lead to the formation of composite films with high crystallinity, good mechanical properties, and biocompatibility.

Summary: This study reports the controlled growth of metastable gallium oxide films by pulsed laser deposition (PLD) and explores a comprehensive phase evolution picture tuned by synthesis parameters, substrate orientations, and Sn dopants. The stabilization of both undoped and Sn-doped α-Ga2O3 films on a-plane sapphire substrates is demonstrated, and Sn dopants can broaden the growth window of α-Ga2O3. Sn-doped ε-Ga2O3 is more favored than β-Ga2O3 to be stabilized on c-plane substrates, and oxygen pressure is critical for ε-Ga2O3 formation. The structural impact on thermal transport among these metastable Ga2O3 films is investigated, showing different thermal conductivities. This study provides a synthesis guideline for metastable Ga2O3 polymorphs and insights into selective phase stabilization of transition metal oxides.

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: TiAlN/TiAlCN multilayer coatings with different modulation ratios were prepared, and their microstructure, composition, surface morphology, mechanical and tribological properties were investigated. The results showed that the modulation ratio influenced the distribution and composition of the composite structure at the interface of the coatings. The multilayer coating with a modulation ratio of 1.0 exhibited the highest hardness due to the difference in modulus, increase in sp3-C bonds, and strengthening of fine grains. The friction experiment revealed that the wear rate decreased significantly with a decrease in modulation ratio, and the multilayer coating with a modulation ratio of 0.7 had a relatively low coefficient of friction and the lowest wear rate.

Summary: For the first time, the possibility of vacuum depositing complex metal-containing organic-inorganic coatings with selective stimulating and inhibitory activity against microorganisms (C. albicans, E. coli, Lactobacillus rhamnosus GG) has been demonstrated. The coatings, based on CaH2/Mg, citric acid, glucose, and ammonium phosphate, were deposited using a low-energy electron beam, considering the features of chemical interlayer interactions. These coatings, which absorb atmospheric moisture, cannot be produced using other vacuum methods. A comparative analysis of the calcium and magnesium effect on stimulating the growth of Lactobacillus rhamnosus GG was conducted. The resulting coatings can be used to modify the surface of pessaries.
