Abstract:
1. A semiconductor element comprising: a first electrode; a semiconductor layer containing an organic material; an insulating film which electrically insulates the first electrode and the semiconductor layer; a second electrode which injects electrons into the semiconductor layer; and a third electrode which injects holes into the semiconductor layer, wherein the third electrode has at least partially a layer comprising a first composite material wherein the first composite material contains an organic material having a hole-transporting property and a metal oxide, wherein the second electrode has at least partially a layer comprising a second composite material wherein the second composite material contains an organic material having an electron-transporting property and alkaline metal or alkaline earth metal, wherein the layer comprising the first composite material and the layer comprising the second composite material are each in contact with the semiconductor layer, wherein the third electrode is formed of two layers of the layer comprising the first composite material and a conductive layer, and the conductive layer is in contact with the semiconductor layer, wherein the second electrode is in contact with the insulating film, and wherein the third electrode is in contact with the insulating film.
