In this article, photolithographically defined organic thin-film transistors (OTFTs) with improved field-effect mobility and sub-threshold slope were fabricated using two layers of pentacene deposited at different substrate temperatures.Abstract:
Using two layers of pentacene deposited at different substrate temperatures as the active material, we have fabricated photolithographically defined organic thin-film transistors (OTFTs) with improved field-effect mobility and subthreshold slope. These devices use photolithographically defined gold source and drain electrodes and octadecyltrichlorosilane-treated silicon dioxide gate dielectric. The devices have field-effect mobility as large as 1.5 cm/sup 2//V-s, on/off current ratio larger than 10/sup 8/, near zero threshold voltage, and subthreshold slope less than 1.6 V per decade. To our knowledge, this is the largest field-effect mobility and smallest subthreshold slope yet reported for any organic transistor, and the first time both of these important characteristics have been obtained for a single device.read more

Improved Performance forOTFTwithHfTiO2as gatedielectric byN20annealing
TL;DR: In this article, the authors show that pentacene has a strong tendency to form that OTFT withgatedielectric annealed in N20 molecular crystals and has larger dielectric constant, smaller threshold evaporation which is animportant factor for voltage, smaller sub-threshold slope and larger highcarrier mobility.

Pentacene-based organic thin-film transistors
TL;DR: In this paper, the authors show that the large sub-threshold slope typically observed is not an intrinsic property of the organic semiconducting material and that devices with sub-reshold slope similar to amorphous silicon devices are possible.
