p-Type Transparent Copper Iodide Thin Films for Electronics and Optoelectronics
This community focuses on the synthesis, structural characterization, and electronic optimization of copper iodide (CuI) thin films, specifically developing them as p-type transparent semiconductors and conductors.
The work centers on depositing high-quality CuI films via solution processing, sputtering, and pulsed laser deposition. A dominant strand of research involves doping strategies—using sulfur, zinc, or cesium—to enhance hole mobility and conductivity while maintaining optical transparency. These engineered films are applied in p-channel transistors, transparent conducting electrodes, and heterojunction devices for UV photodetection. The community also investigates the fundamental limits of carrier transport and the role of intrinsic defects in determining the material's electrical performance.
The community is most prominent in silver research, accounting for 0.8% of all silver-related papers, and in iodine research, representing 0.4% of that element's output. It also holds a 0.4% share of bromine research.
The community comprises 4,433 papers, with the highest publication volume in the Journal of the Optical Society of America, Journal of Physics and Chemistry of Solids, and physica status solidi (b).
Recent work continues to refine deposition techniques, such as post-iodination sputtering and room-temperature wafer-scale synthesis, to improve the transparency and conductivity of sulfur-doped copper iodide. Additional recent studies examine the role of doping in UV detection and the influence of laser fluence on the structural and electrical properties of the films.
