Both organic thin film transistors (OTFTs) and organic single crystal field effect transistors (OFETs) are of primary interest for the characterization of the transport properties of novel organic materials.@footnote 1@ At the present, a comparison between these two approaches shows that the mobility is low on the deposited thin films, which is attributed to interface and grain boundary phenomena.@footnote 2@ In the case of single crystal OFETs there are several key factors, which affect their performance (the mobility and on/off ration). We will report on optimization of the OFET fabrication process, which allowed to reproducibly obtain the values of µ ~ 10 cm@super 2@/Vs. To the best of our knowledge, this is the highest mobility reported for organic field-effect devices at room temperature. In addition, in contrast to the TFTs, our devices demonstrate the threshold-less operation, gate voltage in-dependent mobility and very small subthreshold slope. @FootnoteText@@footnote 1@D.
