Summary: In this study, growth of Sb2Se3 thin films was attempted using pulsed laser deposition technique with presynthesized ball-milled Sb2Se3 compound material as a source. The films grown at 320 degrees C exhibited crystalline orientation along (020) and presence of Sb2O3, confirmed by Raman and X-ray photoelectron spectroscopy analysis. Optical transmittance studies revealed a bandgap of approximately 1.29 eV, matching reported values, with absorption values around 10^6 cm(-1) in the visible region. Scanning electron microscopy showed films grown at 320 degrees C to have a crack-free surface and a thickness of around 1 μm. Energy-dispersive X-ray spectroscopy indicated near stoichiometric compositional values with slight selenium deficiency. Resistivity measurements showed Sb2Se3 films grown at 320 degrees C to have a value of approximately 6 x 10^8 Omega-cm, and hot point probe measurement confirmed the film to be a p-type semiconductor.

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: This work focuses on improving the quality of highly (100)-oriented SnSe thin films for thermoelectric applications. By controlling key parameters during pulsed-laser deposition and performing vacuum thermal annealing, the film quality was enhanced. The best crystal quality and uniform orientation were achieved on SiO2/Si substrate at 673 K followed by thermal annealing at 673 K for 30 min, showcasing promising Seebeck coefficient and power factor values.

Summary: In this study, thin films deposited from the plasma phase of oxazoline precursors were investigated as an alternative approach for electrode functionalization, showing the advantage of being substrate independent and allowing spontaneous binding of biomolecules in physiological buffer. These films were further utilized to develop an immunosensor with a low detection limit for free epithelial cell adhesion molecule.

Summary: A thin film of uranium oxide was successfully deposited on a single crystal substrate with a specific orientation using polymer assisted deposition. The sample was confirmed to be alpha-U3O8 through a combination of X-ray and neutron reflectometry techniques. The film had a thickness of 17 nm and was covered by a less dense capping layer, possibly due to surface water adsorption.

Summary: CuSbSe2 has shown promising photovoltaic properties for thin film solar cells due to its environmentally friendly constituent elements. High-quality CuSbSe2 thin films were prepared by pulsed laser deposition and in-situ annealing. The results indicated a reduction in Sb2Se3 and Cu3SbSe3 content in the films after annealing, with an estimated atomic ratio of Cu:Sb:Se close to the stoichiometry ratio of CuSbSe2. The optical band gap of the annealed film met the requirements for solar cell absorber layers.

Summary: This research presents a synthesis method for a thin-film cathode that can enhance the electrochemical performance of batteries. V2O3 thin films were successfully synthesized on graphene/aluminum foil and tested as cathodes. The experimental results demonstrate that the V2O3 thin films exhibit superior electrochemical properties, especially with the addition of tin (5 mol%) which improves the initial capacity and cycling performance of the batteries.

Summary: This paper reports on the growth of epitaxial Fe3Si ultra-thin films by pulsed laser deposition on SrTiO3(001) substrates and analyzes the effect of deposition temperature on the structural, morphological, and magnetic properties of the films. The results show that the best magnetic response is achieved at 200°C, which represents the optimal compromise between phase purity and interface quality.
