Metal Oxide Thin Films for Gas Sensing, Photocatalysis and Thin-Film Transistors
This community develops metal oxide materials, primarily zinc oxide, tin oxide, and indium oxide, for use in gas sensors, photocatalytic degradation of pollutants, and thin-film transistors.
The research focuses on synthesizing and characterizing thin films and nanostructures of metal oxides, with a strong emphasis on doping strategies to enhance performance. Key applications include chemiresistive gas sensors for detecting specific gases at room temperature, photocatalysts for environmental remediation and water treatment, and semiconducting channels for thin-film transistors. Common fabrication methods include spray pyrolysis and sol-gel processes, while characterization relies heavily on structural and optical analysis. The work frequently involves heterostructures and nanocomposites to improve sensitivity, activity, or electrical properties.
The largest share of the community's output is found in tin research, accounting for 20.2% of all tin research, and 7,080 papers here. Zinc research follows with 14.2% of all zinc research and 12,467 papers, while indium research represents 17.9% of all indium research and 7,026 papers.
The community comprises 36,377 papers, published most frequently in Thin Solid Films, Applied Physics Letters, and Sensors and Actuators B Chemical.
Recent work continues to explore gas sensing applications, including sensors for NO2, CO, and CH4, as well as the development of thin-film transistors using materials like InZnO and IGZO.
