Organic electronic devices and their applications — •Paul Heremans — IMEC, Leuven, Belgium

Organic electronics will be enabled not only by thin film transistors, but also by such devices as memory and diodes.

In this presentation, we will focus on devices that can enable RFID applications or other autonomous sensor tags. Such applications require in particular transistor circuits operating at low voltage. Several strategies could be followed to achieve this, and we will provide a comparison between the performance and limitations that can be expected by complementary logic versus ambipolar logic. A second device needed for RFID applications is a diode for high frequency rectification. We will start by outlining the specifications required for these diodes. Then, we will show the state of the art of the performance that has been achieved to this date by diodes made using, on the one hand, transistors with the drain shorted to the gate, and, on the other hand, ``Schottky'' diodes with a rectifying metal contact. Finally, results of practical organic RFID tags using Schottky diodes will be shown.
