Characteristics of High-Performance Ambipolar Organic Field-Effect Transistors Based on a Diketopyrrolopyrrole-Benzothiadiazole Copolymer
TLDR
In this paper, the authors report the device characteristics of ambipolar thin-film transistors (TFTs) based on a diketopyrrolopyrrole-benzothiadiazole copolymer.Abstract:
In this paper, we report the device characteristics of ambipolar thin-film transistors (TFTs) based on a diketopyrrolopyrrole-benzothiadiazole copolymer. This polymer semiconductor exhibits the largest comparable electron and hole mobility values in a single organic semiconductor. The key to realizing such high mobility values, which are >;0.5 cm2 / V · s, is molecular design, i.e., the use of suitable surface treatments of the source/drain contact electrodes and device architectures, particularly top-gate configurations. The subthreshold characteristics of the TFT devices are greatly improved by the use of dual-gate device geometry. We also report the first measurement of the velocity distribution of electron and hole velocities in an ambipolar organic semiconductor.read more

TL;DR: It is demonstrated that the use of an appropriate hydroxyl-free gate dielectric—such as a divinyltetramethylsiloxane-bis(benzocyclobutene) derivative (BCB; ref. 6)—can yield n-channel FET conduction in most conjugated polymers, revealing that electrons are considerably more mobile in these materials than previously thought.

Stability of n-type doped conducting polymers and consequences for polymeric microelectronic devices
TL;DR: In this paper, the authors derived the stability requirements on electrode potentials of n-type doped conducting polymers and compared the predictions with experimental data on stability of polymers, and showed that an electrode potential of about 0 to + 0.5 V (SCE) is required for stable polymers.
