Summary: By studying the lattice strain in rutile-type RuO2 epitaxial thin films grown at different temperatures, it was found that the strain is influenced by growth-mode-induced effects and thickness. Within a certain range, the lattice strain had no significant impact on the electrical properties of RuO2, ensuring its reliable applications as catalysts and electrodes.

Summary: This study focuses on quantifying the impact of microstructure on the functionality of titanium dioxide films caused by minor changes in the fabrication process. Thin titanium dioxide films are deposited using sputtering with variations in target composition and working environment. Various characterization techniques are employed to quantitatively analyze the phase, chemical constitution, composition, thickness, roughness, density, etc. of the films and their link to electronic structure, electrical, optical, and surface characteristics. The insights from this study can guide the experimental design for fabricating films with desired functionalities by considering the tolerance range.

Summary: This study examines the tribvovoltic performance of TiO2 thin films in contact with metals of varying work functions. It is found that the current density is not strongly correlated with the work function of the contact metal but is strongly correlated with the contact area. The thermoelectric coefficients of different metals at the metal-semiconductor interface also show a clear correlation with the tribvovoltic current density.

Summary: Nanocrystalline structure tungsten oxide thin films were successfully deposited on fluorine-doped tin oxide substrates via an electrochemical deposition method. The films exhibited temperature dependent structural transitions and showed excellent electrochromic performances, including fast-switching speed, significant optical modulation, high coloration efficiency, and cycling stability. Additionally, an electrochromic device was assembled using a complementary electrode of NiO film, which also demonstrated fascinating performance.

Summary: Investigation of trilayer structures composed of nominally 45 nm GaN:Mg / 5 nm (Ga,Mn)N / 45 nm GaN:Mg prepared by molecular beam epitaxy on GaN-buffered Al2O3 substrates reveals that the indirect co-doping by holes from the cladding layers may not significantly alter the spin-spin interaction in (Ga,Mn)N, possibly due to the presence of residual Mn in the cladding layers. More technological efforts are suggested to promote the carrier-mediated ferromagnetic coupling in Mn-enriched GaN, particularly at elevated temperatures.

Summary: The research aims to examine the properties required for producing thin films of TiO2 using RF plasma, with the ability to modify the films through heating to induce defects and change their characteristics. Different deposition regimes were studied to minimize unwanted contaminants and the resulting TiO2 films showed a lower cost alternative to single-crystal TiO2 with known elemental composition and modifiable properties.

Summary: Electrochromic technologies have gained attention for their energy-saving performance. This study electrodeposited nanostructured tungsten trioxide films to enhance their electrochromic properties by controlling the pH of electrolytes. Electron microscopy and spectroelectrochemical analysis showed that smaller grain sizes resulted in larger electrochemical reactive surface areas and shorter ion diffusion lengths, achieving efficient ion intercalation and deintercalation.
