Progress in organic field-effect transistors and its applications

Organic field-effect transistors(OFETs)are the transistors using organic semiconductive materials as the active layers. In comparison with conventional inorganic transistors, OFETs have attracted extensive attention due to their potential applications in large area and flexible opto-electronic devices, such as organic light emitting diodes (OLEDs), organic photo detectors (OPDs), organic solar cells, pressure sensors, organic memory elements, flexible flat panel displays, electronic papers, and so on. The device structure and operating principle of OFET are briefly introduced in the beginning of the paper. The development of organic materials, fabrication technologies and potential applications of OFETs in the past few years are reviewed comprehensively. Finally, the development of OFETs in the future is prospected.
