Zinc Oxide Thin Films and Nanostructures for Optoelectronics and Photocatalysis
This community focuses on the synthesis, structural characterization, and functional application of zinc oxide (ZnO) in thin-film and nanostructured forms, primarily for use in solar cells, UV photodetectors, and photocatalytic degradation of pollutants.
The work centers on depositing ZnO via spray pyrolysis, sol-gel, and magnetron sputtering to create films, nanorods, and nanowires. A significant portion of the research involves doping these structures with aluminum, cobalt, or rare-earth elements to tune optical and electrical properties. Applications named in the titles include enhancing photocatalytic activity for dye degradation, improving performance in solar cells, and developing UV photodetectors. The recurring methods emphasize controlling crystal structure and morphology to optimize bandgap properties and defect states, with a strong emphasis on the interplay between structural integrity and optical response.
Zinc is the dominant element, accounting for 8.3% of all tracked zinc research and 22,240 papers within this group. Other significant elements include tin (1.1% of tin research) and indium (1.3% of indium research), reflecting the use of these materials in heterojunctions and doping strategies.
The community comprises 26,954 papers, with the highest publication volumes in the Journal of Applied Physics, Thin Solid Films, and Applied Physics Letters.
Recent work continues to explore doped ZnO thin films for functional applications, including UV-visible photodetectors and solar-driven photocatalysis. Specific recent studies examine the role of transition metal doping in tuning band gaps and the use of ZnO nanostructures in photovoltaic devices, consistent with the broader community focus on optoelectronic and catalytic performance.
