Printed and Thin Film Transistors and Memory

Flexible transistor circuits using new compounds
Traditionally, semiconductors are made as crystalline as possible to optimise their performance. The new transistors variously use thin films of organic or inorganic compounds as the semiconductors and gate dielectrics, enabling flexible transistor circuits. One printable inorganic semiconductor favoured by Toppan Printing and Tokyo Institute of Technology is an amorphous combination of InGaZnO, for example, and it can be cured at low temperature. Electrodes in the new transistors are sometimes metal but sometimes they consist of conductive organic compounds.
