Copper Oxide Thin Films and Nanoparticles for Optoelectronics and Photocatalysis
This community focuses on the synthesis, structural characterization, and property tuning of copper oxide materials, specifically CuO and Cu2O, primarily in thin film and nanoparticle forms. The work is driven by applications in solar cells, gas sensing, and photocatalytic degradation of pollutants.
The research centers on depositing copper oxide films using techniques like magnetron sputtering, spray pyrolysis, and chemical synthesis, followed by rigorous analysis of their structural, morphological, optical, and electrical properties. A significant portion of the work involves doping these films with elements such as zinc, tin, magnesium, or aluminum to modify bandgaps and enhance performance for specific uses. Recurring applications include heterojunction solar cells, visible-light photocatalysis for wastewater treatment, and gas sensing. The community also investigates the fundamental mechanisms of oxidation, defect formation, and phase transitions in copper oxides to better control material behavior.
Copper is the dominant element, accounting for 60% of the community's papers, which represent 60% of all tracked copper research. Oxygen and zinc are the next most frequent elements, with zinc contributing 249 papers, or 10% of tracked zinc research.
The community comprises 3,775 papers, published most frequently in Thin Solid Films, Applied Surface Science, and the Journal of The Electrochemical Society.
Recent work continues to explore doping strategies and defect engineering in CuO thin films for antibacterial and photodetection applications, as well as the synthesis of copper oxide nanoparticles for photocatalysis and gas sensing.
