Control of threshold voltage and hysteresis in organic field-effect transistors

Applied Physics Letters (2009)

Hideyuki Kawaguchi Masateru Taniguchi Tomoji Kawai

We have fabricated organic field-effect transistors that have hybrid gate insulating films, consisting of an inorganic insulating film and a cross-linked insulating polymer. The hybrid insulating films allow the capacitance to be controlled easily, which makes it possible to reduce the influence of trapped charge at the insulator-semiconductor interface. As a result, the threshold voltage and the threshold voltage shift can be controlled. The increased capacitance of the insulating film results in low driving voltages and small hysteresis in the transfer characteristics.
