Organic Thin-Film Transistors for AMOLED Applications

In this article we present an integration technique to improve the performance of DNTT-based TFTs in inverted coplanar architecture. An alkanethiol treatment of the source- and drain-electrodes was employed to reduce the occurring Schottky barrier formed at the metal-semiconductor interface. To evaluate the influence of the alkanethiol treatment (un-)treated OTFTs were integrated and compared regarding their electrical characteristics. Furthermore, first electronic circuits, on the one hand inverter in single-type technology, and on the other hand organic light emitting diode (OLED) devices controlled by a treated DNTT-based TFT, were fabricated and analysed.
