ABSTRACT:
It is an object to provide an organic field effect transistor including an electrode which can reduce an energy barrier at an interface between a conductive layer and a semiconductor layer, and a semiconductor device including the organic field effect transistor. A composite layer containing an organic compound and an inorganic compound is provided in at least part of one of a source electrode and a drain electrode in an organic field effect transistor, and as the organic compound, a carbazole derivative represented by the general formula (1) is used. By providing the composite layer in at least part of one of the source electrode and the drain electrode, an energy barrier at an interface between a conductive layer and a semiconductor layer can be reduced.
