Charge transport in copper phthalocyanine (CuPc), partially fluorinated CuPc (F4CuPc), and fluorinated CuPc (F16CuPc) based organic thin film transistors is studied using dual SiO2/polymethylmethacrylate gate dielectrics. We demonstrate the strong influence of air/moisture induced electron traps on electron transport when the lowest unoccupied molecular orbital is close to the vacuum irrespective of hydroxyl-free dielectrics used in the devices.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.
