Abstract(in English) Organic static induction transistor (SIT) with vertical structure has been expected for low-voltage driving and high speed operation devices due to short channel length than lateral type transistor so that a channel length is equivalent to the thickness of an organic semiconductor film. However, the organic SIT has problems such as low on/off ratio and low current value. We found that there was high correlation between the modulation in static characteristic of a pentacene SIT and an interface condition of organic semiconductor layer/source electrodes. We researched on the influence of changing of the interface conditions on a characteristic of organic SIT. As a result, in order to achieve the high on/off ratio and high current value in the organic SIT, it is necessary to form the barrier on a source electrode. The barrier functions as controlling a tunnel current from a source electrode by applying the gate voltage.
