Role of the electronically-active amorphous state in low-temperature processed In₂O₃ thin-film transistors

Abstract

Process-structure-transport relationships in low-temperature-processed, blade-coated In2O3 transistors using sol–gel and combustion chemistries are explored with X-ray scattering techniques. Electron mobility of ≈4.5 cm2 V−1 s−1 is achieved at ≈220 °C.

Recent Advances in Metal-Oxide Thin-Film Transistors: Flexible/Stretchable Devices, Integrated Circuits, Biosensors, and Neuromorphic Applications

“…Recently, a solution-based process for metal-oxide semiconductor thin film has been actively studied. Additionally, the solution process has various methods for fabricating metal-oxide semiconductors such as spin coating [25,[32][33][34][35], spray coating [26,36], blade coating [37,38], flexographic printing [27], and inkjet printing [28,39]. Most solution-based processes have advantages for manufacturing flexible and printable devices because of the low annealing temperature.…”

Quantum Confinement and Thickness‐Dependent Electron Transport in Solution‐Processed In2O3 Transistors

“…[6] On the other hand, recent progress in solutionphase processing of semiconductor films has allowed the deposition of ultrathin layers (<10 nm) and the demonstration of numerous devices. [7][8][9][10][11][12][13] Despite the promise of scalable manufacturing, however, solution-based processing is often associated with the unintentional introduction of a high density of structural and chemical defects as compared to high-quality epitaxial layers. Therefore, an improved understanding of the relationship between the semiconductor's dimensionality and electronic properties is required.…”
