The Market for Organic and Printed Electronics

Then there is recent success with transistors using silicon nanoparticles in organic inks. It used to be believed that both inorganic and organic semiconductors had to be as crystalline as possible to give high charge carrier mobility and therefore high frequency of operation in transistors. However, the InGaZnO transistors being printed by Tokyo Institute of Technology and Toppan Printing Japan are amorphous. An organic carrier is used in the ink. The resulting transistor arrays form backplanes for flexible electrophoretic displays.
