Abstract: A method of forming an organic thin film includes developing organic molecules having a hydrophilic portion and a hydrophobic portion on a water surface, and compressing the organic molecules thereby to form a monomolecular layer of a predetermined surface pressure. The monomolecular layer is brought into contact with a given substrate. Then, the substrate to which the monomolecular layer is adhered, is pulled at such a rate that the surface pressure is not substantially lowered, thus transferring the monomolecular layer onto the substrate.

Abstract: An organic thin film element has a structure in which an organic thin film layer, an insulating layer, and a back electrode are sequentially formed on a substrate obtained by forming an electrode, an insulating layer and a layer consisting of polycyclic aromatic group molecules or a derivative thereof or a carbon layer having a graphite structure on the surface of a substrate main body. An effect of controlling the orientation of the organic thin film layer can be enhanced by the surface layer of the substrate similar in chemical structure to molecules constituting the organic thin film layer. A neutral-ionic transition of a complex can be effectively caused by an electric field applied from the electrodes.

Abstract: A semiconductor luminescent device having a structure in which an organic layer is sandwiched between first and second electrodes and having an organic/inorganic junction in which at least the first electrode of the first and second electrodes consists of an n-type inorganic semiconductor. A junction between the first electrode and the organic layer forms a blocking contact against electron injection from the first electrode into the organic layer and hole injection from the organic layer into the first electrode. A junction between the second electrode and the organic layer facilitates injection of holes from the second electrode into the organic layer.

Abstract: An organic electroluminescent device is constituted by first and second electrodes opposing each other and a multilayered body having a plurality of organic films sandwiched between the electrodes and including an electroluminescent layer. A donor impurity is doped in a first organic film in contact with the first electrode, and an acceptor impurity is doped in a second organic film in contact with the second electrode. A third organic film sandwiched between the first and second organic films serves as an electroluminescent layer. A material having a band gap narrower than those of the first and second organic films is selected as a material of the third organic film so as to confine carriers. No impurity is doped in the third organic film.

Abstract: An organic film forming apparatus includes a trough storing water therein and a work drive device for moving a work with respect to the trough. The surface of the water is partitioned by a rod into a first developing region on which a monomolecular film is developed and a second developing region on which no monomolecular film is developed. The work is moved by the device through the developed monomolecular film so as to adhere the film on the surface of the work. The device has a holding mechanism which has a holding portion engaged with the work, and which holds the work so that when the work passes through the developed monomolecular film, the holding portion is away from the film or passes through the film after almost the entire work passes through the film.

Abstract: A film manufacturing method which utilizes a trough storing a liquid therein. The liquid surface of the liquid forms a developing region in which a monomolecular film of organic molecules is developed. The developed monomolecular film is compressed by a barrier to a predetermined surface pressure. A workpiece having a build-up surface is moved by a vertical moving mechanism in a direction perpendicular to the developing region through the monomolecular film while being moved ahead of the build-up surface in a horizontal direction by a horizontal moving mechanism, so that the monomolecular film is built up on the build-up surface.
