Influence of thermal treatment on electronic properties of inkjet-printed zinc oxide semiconductor

Additive manufacturing of electronic devices using inkjet printing provides a potential alternative approach in substitution for conventional fabrication processes. However, the complex nature involves liquid deposition and film formation from vaporization solvent, which makes it different created by methods. Inkjet zinc oxide (ZnO), is widely utilized semiconductor, produces polycrystalline composed nano-size grains, could significantly influence properties printed film. In this study, low-temperature annealing was employed to treat inkjet-printed ZnO UV photodetection application, its on electrical studied. Band bending characterized Mott-Schottky plot examines charge distribution films. It found that has improved properties, be attributed reduction band due merging grains. The treatment also helps reduce impurities film, such as hydroxide complexes, common solution-derived Hence, study pay way improvement functional materials.
