Amorphous Oxide Thin-Film Transistors for Flexible and Integrated Electronics
This community develops semiconductor devices using amorphous metal oxides, primarily for flexible displays, large-area electronics, and low-power integrated circuits.
The work centers on the synthesis and characterization of thin-film transistors (TFTs) using materials such as indium-gallium-zinc oxide (IGZO), indium tin oxide (ITO), and zinc oxide. Key fabrication methods include atomic layer deposition and solution processing, with significant focus on optimizing electrical stability, carrier mobility, and gate dielectric integration. Applications span display backplanes, flexible electronics, and three-dimensional integrated circuits, where these oxide semiconductors serve as the active channel material.
The community is most concentrated in research on Indium, comprising 2.9% of all tracked Indium research, and Zinc, comprising 1.4% of all tracked Zinc research. Indium also represents the largest paper count within this group, with 4,280 papers.
The community comprises 11,588 papers, publishing most frequently in Applied Physics Letters, IEEE Electron Device Letters, and the SID Symposium Digest of Technical Papers.
Recent work continues to focus on the materials science of amorphous IGZO, including the suppression of trap states for low-power applications, the development of vertical dual-gate structures for 3D memory integration, and the fabrication of backplane transistors for information displays.
