To reach this frequency is in no way trivial, and in particular requires a minimum mobility of charge carriers within the organic field effect transistors. This important issue will be discussed below. It has to be noted, however, that in view of the technological applications, a reliable and constant device performance may be even more important than a peak performance of the individual circuits. 

Over the last two decades the charge carrier mobilities of organic materials have shown a rather rapid increase today organic field effect transistors can be built with performances [14, 15] that can compete with FETs based on polycrystalline silicon [16].

In recent years great effort has been devoted to conjugated polymers as organic field-effect transistor (OFET) active layers [1]. An important parameter relevant to the operation of an OFET is the charge carrier mobility which determines the overall performance of any polymer-based devices.

The semiconductor insulator interface is the primary factor that determines the field-effect mobility of charge carriers in an organic field effect transistor (OFET). Vapor phase or solution based treatments with an alkyl silane or silazine group forms a self-assembled monolayer on the surface of the insulator. Such treatments prior to the deposition of the semiconductor reduces the surface energy which improves the...
