Thin film transistor array passes "see through" test
Transparent thin-film transistors (TFTs) are the most fundamental functional components of "see through" electronics – a fast-moving and demanding field where devices must offer high optical transparency, low-power consumption and be compatible with diverse, low-cost substrates.
Scientists in China have developed high-performance transparent TFTs with Sb-doped SnO2 nanocrystal channels that can be fabricated at room temperature. The production method overcomes some of the challenges faced in the application of portable and transparent TFTs powered by a battery.
The room temperature process is compatible with temperature-sensitive substrates, which makes it a strong candidate for bendable electronics such as large-area displays and chemical sensors.
Having developed a series of prototype arrays on glass, the team is now investigating the production of Sb-doped SnO2 nanocrystal TFTs on flexible substrates, such as plastic and paper.
The researchers presented their work in Nanotechnology.
