Flexible organic transistors, such as this one developed last year at the University of Tokyo, will enable a wide variety of flexible computing devices when commercialized.
Flexible organic transistors, such as this one developed last year at the University of Tokyo, will enable a wide variety of flexible computing devices when commercialized.

 

The Korea Research Institute of Chemical Technology (KRICT) announced on September 4 that a research team led by Kim Yun-ho and Ka Jae-won successfully developed technology for the fabrication of large-area, low-cost, high-performance organic transistors, a key technology for next-generation displays.

The research findings were published online in the August 21 issue of research journal Advanced Materials

Dr. Kim Yun-ho (second from left) and Dr. Ka Jae-won (far right) with staff at the Korea Research Institute of Chemical Technology.The team was able to develop technology that enables the production of organic semiconductor crystalline thin films in a large area by introducing a technology for liquid crystal surface alignments in order to improve the performance of organic field-effect transistors (OFETs).

With the application of technology, organic thin film transistor devices were able to be made so that they can have charge transfer effects 6 times more than conventional ones. 

Dr. Kim said, "I think that large-area patterning using the unique flow ability of liquid crystalline organic semiconductors, and simple process technology that can increase material properties, will contribute to a decrease in the manufacturing cost of OFET devices. The technology can be used in not only the display field, but also the development of various organic electronic devices, including organic logic circuits where organic semiconductors are used, and organic solar cells.”

The total market for organic electronic devices using organic semiconductors is expected to reach US$4.6 billion by 2018. Among those, the market for organic thin film transistor parts is likely to reach US$1 billion.
