    摘要： An organic semiconductor diode comprises a hole transport layer which is arranged on an anode side and formed of an organic compound having a hole transport capability, and an electron transport layer which is arranged on a cathode side and formed of an organic compound having an electron transport capability. The hole transport layer and the electron transport layer are laminated one upon another. The cathode has a work function close to or smaller than the electron affinity of the electron transport layer, while the anode has a work function larger than that of the cathode. The organic semiconductor diode exhibits nonlinear current-voltage characteristics when a voltage is applied between the hole transport layer and the electron transport layer in contact with each other.

    摘要： An organic semiconductor diode includes at least one hole transport layer which is arranged on an anode side and formed of an organic compound having a hole transport capability, and at least one electron transport layer which is arranged on a cathode side and formed of an organic compound having an electron transport capability. The at least one hole transport layer and the at least one electron transport layer are laminated one upon another. The organic semiconductor diode exhibits nonlinear current-voltage characteristics when a voltage is applied between the hole transport layer and the electron transport layer in contact with each other. The hole transport layer at an anode-side end has an ionization potential larger than an electron affinity of the electron transport layer at a cathode side end.
