Abstract
We describe the importance of a patterned active layer for the fine driving of organic inverters. In the case of a non-patterned inverter, the capacitance as a function of the applied bias in an organic capacitor structure exhibits a slow saturation nature due to the slow movement of charge carriers. Hence, during the operation of organic inverters with non-patterned active layers, the voltage gains inevitably exhibit lower values whereas higher gains are achieved in the case of sharply-patterned pentacene layers. These results suggest that the patterning of the active layer can be a decisive factor for realizing high-performance electronic circuits based on organic semiconductors.
