TL;DR: In this paper, a model to explain the saturation behavior of the top-contact short channel organic transistor was presented, where the doping profile control directly revealed the resistive part for current injection.
Abstract: The contact doping profile is controlled in the top-contact configuration to clarify a transistor operation based on a current injection process from the metal contact to the organic channel in a submicron channel pentacene field-effect transistor. The molecular doping in the pentacene film underneath the metal contact, in which a thin layer of iron (III) chloride was introduced, drastically changes transistor characteristics. The doping profile control directly revealed the resistive part for current injection. A model to explain the saturation behavior of the top-contact short channel organic transistor is presented.

TL;DR: In this article, a 10-nm co-evaporated layer of molybdenum tris-[1,2-bis(trifluoromethyl)ethane-1, 2-dithiolene] and pentacene was deposited under the metal electrodes for this purpose.

TL;DR: In this paper, the field effect in pentacene thin-film transistors was studied using bottom-contact devices with channel lengths below 10nm, and a pair of guarding electrodes as close as 20nm to the two sides of the channel was employed to suppress spreading current.
Abstract: The field effect in pentacene thin-film transistors was studied using bottom-contact devices with channel lengths below 10nm. To suppress spreading current in these devices, which have a small channel width-to-length (W-L) ratio, we employed a pair of guarding electrodes as close as 20nm to the two sides of the channel. The responses of these nanometer scale transistors exhibit good gate modulation. Mobilities of 0.046cm2∕Vs and on/off ratios of 97 were achieved in sub-10-nm transistors. We find that the device response is strongly influenced by the nature of the metal-semiconductor contact.

TL;DR: In this article, a method is proposed to switch between lateral and vertical phase separations in semiconducting 6,13-bis(triisopropylsilylethynyl) pentacene (TIPSE pentaene)/polymer blend films by simply varying the alkyl length of the polyacrylate polymer component.
Abstract: Lateral and vertical phase separations play critical roles in the performance of the next-generation organic and hybrid electronic devices. A method is demonstrated here to switch between lateral and vertical phase separations in semiconducting 6,13-bis(triisopropylsilylethynyl) pentacene (TIPSE pentacene)/polymer blend films by simply varying the alkyl length of the polyacrylate polymer component. The phase separation modes depend on intermolecular interactions between small molecule TIPSE pentancene and polymer additives. The blend film with a dominant vertical phase separation exhibits a significant enhancement in average mobility and performance consistency of organic thin-film transistors.
