Title: Review of flexible and transparent thin-film transistors based on zinc oxide and related materials,
Abstract: Flexible and transparent electronics presents a new era of electronic
technologies. Ubiquitous applications involve wearable electronics, biosensors,
flexible transparent displays, radio-frequency identifications (RFIDs),
etc.Zinc oxide (ZnO) and related materials are the most commonly used inorganic
semiconductors in flexible and transparent devices, owing to their high
electrical performance, together with low processing temperature and good
optical transparency.In this paper, we review recent advances in flexible and
transparent thin-film transistors (TFTs) based on ZnO and related
materials.After a brief introduction, the main progresses on the preparation of
each component (substrate, electrodes, channel and dielectrics) are summarized
and discussed. Then, the effect of mechanical bending on electrical performance
was highlighted. Finally, we suggest the challenges and opportunities in future
investigations.
