Fabrication of GaN nanocrystalline thin films Schottky metal-semiconductor-metal ultraviolet photodetectors

Abbas M. Selman et al.

Summary: Gallium nitride nanocrystalline thin films were successfully prepared on Si substrates using the RF magnetron sputtering method. The films exhibited a smooth surface and regular distribution of GaN nanoparticles with an average size of 10-20 nm. The films also showed promising potential as ultraviolet photodetectors with tunable sensitivity under different bias voltages.

Photocatalytic activity and photoelectrochemical properties of Ag/ZnO core/shell nanorods under low-intensity white light irradiation

M. J. Kadhim et al.

Summary: Zinc oxide (ZnO) nanorod thin films were prepared by CBD and silver (Ag) nanoparticles were synthesized on the surface using electrochemical methods. The average particle size of the Ag/ZnO/glass core/shell nanostructure was 20 nm, exhibiting photocatalytic activity in degrading methylene blue dye under visible light. Annealed Ag/ZnO core/shell nanostructure showed improved degradation efficiency, with specific capacitance of the electrodes remaining at approximately 99%.

Thermal studies on chemical bath deposited thermochromic VO2 thin film for energy efficient glass windows

Adisu Tsige et al.

Summary: Thermochromic vanadium dioxide (VO2) thin films were successfully synthesized using acidic Chemical Bath Deposition (CBD) method in this study. Differential Scanning Calorimetry (DSC) revealed a critical transition temperature of 68 degrees C for the thin films, while X-ray diffraction (XRD) showed a direct relationship between crystalline size and Full Width Half Maxima (FWHM) with annealing temperature, indicating the potential of CBD-synthesized VO2 thin films for smart window applications in the future.
