Japan Researchers Create Advanced Thin Film Transistors

Tokyo, July 14 (Jiji Press)--A Japanese research group has developed a new method to produce organic thin film transistors whose performance is more than 100 times higher than those made through existing methods.
The outcome of the research led by the National Institute of Advanced Industrial Science and Technology, or AIST, was published in the electronic version of British journal Nature on Wednesday.
The outcome could contribute to the development of bendable televisions and solar panels. TFTs are currently used in flat-panel TVs.
The new method features a "double shot ink-jet printing" technology, by which solution of organic semiconductors and antisolvent are sprayed alternately on a sheet and then organic TFTs are crystallized.
The technology enabled production of flat TFT layers, which is difficult by conventional ink-jet printing methods.
The new method can also cut energy use and costs, as it works at ordinary temperature and atmospheric pressure.
The AIST hopes to collaborate with companies to put the method to practical use as early as possible.
