There is provided a negative-resistance device which is easier to manufacture and can be manufactured at a lower cost as compared with the prior art, and yet has a comparatively large PV ratio, and a method for manufacturing the same. The negative-resistance device is a molecular-doped negative-resistance device which comprises a molecular-doped layer (2) made of an electron transporting lower molecular organic compound, in which the molecular-doped layer (2) is formed to be sandwiched between a pair of electrodes (2, 4), in which respective molecules of said electron transporting lower molecular organic compound are isolated from one another by an electrically insulating organic polymer, and in which said molecular-doped negative-resistance device has a negative-resistance. By doping the lower molecular organic compound in the electrically insulating organic polymer, the molecular-doped layer (3) has a multiple barrier type molecular doping structure, such that contacts each between the organic polymer and a molecule of the lower molecular organic compound are repeated in an alternate order of the organic polymer and the molecule of the lower molecular organic compound. The lower molecular organic compound is preferably a triphenyldiamine derivative or 8-hydroxy-quinoline aluminum, and the organic polymer is poly (N-vinylcarbazole) or polystyrene. <IMAGE> |
