Abstract
Solution-processed amorphous oxide semiconductor thin films contain poor metal-oxygen-metal (M-O-M) networks and numerous impurities, making it difficult to manufacture high-performance semiconductor devices with excellent stability. In this study, we enhance the electrical performance and device stability of solution-processed oxide thin-film transistors (TFTs) by incorporating water molecular oxidants. In solution, a water molecule can be easily incorporated by adding deionized water (DW) to the precursor solution. The DW-incorporated precursor solutions induced the production of oxide semiconductor thin films with improved M-O-M networks and fewer defect states. Therefore, compared to conventional case, the DW-incorporated indium zinc oxide (InZnO) TFT showed improved device performances and significantly reduced changes of threshold voltage under positive gate bias stress and negative gate bias/illumination stress conditions. This approach of incorporating DW into the precursor solutions provides a promising route for fabricating high-quality amorphous semiconductor films and transistor devices.
期刊介绍:
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
