AbstractOrganosilane self-assembled monolayers, embedded in organic single-crystal field-effect transistors, significantly affect subthreshold properties in the transfer characteristics. The monolayer of either polarized or nearly unpolarized molecules is deposited on a SiO2/doped Si substrate before softly attaching a rubrene thin single crystal to form the “laminated crystal” transistors. As a result of effective passivation of the SiO2 surface, the device has achieved a subthreshold swing as low as 0.11 V/decade. It is also demonstrated that threshold gate voltage is shifted by polarization of the monolayers, indicating that threshold of the device is adjustable by the choice of silane materials. Both of the functions are closely associated with low-power applications such as logic-circuit components.

Abstract Transistors, the most important logic elements, are maintained under dynamic influence during circuit operations. Practically, circuit design protocols and frequency responsibility should stem from a perfect agreement between the static and dynamic properties. However, despite remarkable improvements in mobility for organic semiconductors, the correlation between the device performances achieved under static and dynamic circumstances is controversial. Particularly in the case of organic semiconductors, it remains unclear whether parasitic elements that relate to their unique molecular aggregates may violate the radiofrequency circuit model. Thus, we herein report the manufacture of micrometre-scale transistor arrays composed of solution-processed organic semiconductors, which achieve near very high-frequency band operations. Systematic investigations into the device geometrical factors revealed that the radiofrequency circuit model established on a solid-state continuous medium is extendable to organic single-crystal field-effect transistors. The validity of this radiofrequency circuit model allows a reliable prediction of the performances of organic radiofrequency devices.
