Organic thin-film transistors with a photo-patternable semiconducting polymer blend

Organic polymer thin-film photo-transistors

We have investigated the effects of illumination, both broadband and monochromatic, on the electrical performance of organic polymer thin-film transistors (OP-TFTs). In each case, providing the illumination is sufficiently absorbed by the organic polymer, the drain current of a device biased in the OFF-state is significantly increased. We have observed increases in the OFF-state drain current a...

Hamilton and Jerzy Kanicki The University of Michigan, Department of Electrical Engineering and Computer Science, Solid-State Electronics Laboratory, 1067 BIRB, 2360 Bonisteel Blvd, Ann Arbor, MI 48109-2108, USA. ABSTRACT Organic polymer based thin-film transistors (OP-TFTs) look very promising for flexible organic electronics. In this paper, we describe devices base...

Field-Effect Mobility of Organic Polymer Thin-Film Transistors

We present a method of extracting the field-effect mobility from the transfer characteristics of organic polymer thin-film transistors (OP-TFTs), in both the linear and saturation regimes, by accounting for the dependence of the mobility on the gate bias, which translates to a dependence on the accumulated density of majority charge carriers in the channel. This method is compared to the common...

Organic thin film transistors and polymer light-emitting diodes

To fully realize the advantages of organic flexible electronics, patterning is very important. In this paper we show that a purely additive patterning technique, termed polymer inking and stamping, can be used to pattern conductive polymer PEDOT and fabricate sub-micron channel length organic thin film transistors. In addition, we applied the technique to transfer a stack of metal/conjugated po...
