Abstract:
1. A transistor, comprising: a first gate electrode; a second gate electrode; a first gate insulating layer disposed between the first gate electrode and the second gate electrode; a first interlayer disposed between the first gate insulating layer and the second gate electrode and containing a first organic material; an organic semiconductor layer disposed between the first interlayer and the second gate electrode; a second interlayer disposed between the organic semiconductor layer and the second gate electrode and containing a second organic material; a second gate insulating layer disposed between the second interlayer and the second gate electrode; and a source electrode and a drain electrode disposed between the first interlayer and the second interlayer and injecting carriers into the organic semiconductor layer, an ambipolar property being imparted to only a part of the organic semiconductor layer that contacts with the first interlayer and the second interlayer under an action of the first interlayer and a second interlayer.
