Research Projects
Organic Transistors Application of printing methods in producing organic transistors has promised low-cost electronics, but a printed transistor has a poor performance due to the thick semiconductor layer. Also, most of organic transistors operate at high voltages (> 40V). We are investigating two types of organic transistors, OMESFET and dual gate transistor, to overcome the voltage problem and enhance the performance in a thick film transistor.
