摘要： PROBLEM TO BE SOLVED: To allow stable electron emission at low voltage by forming an electron emitting element from an electron supply layer made of a metal or a semiconductor and formed on an ohmic electrode, an insulator layer formed on the electron supply layer, and a metallic thin-film electrode formed on the insulator layer, and setting the film thicknesses of the electron supply layer and the insulator layer at specific numerical values. SOLUTION: When electrons are injected into an electron supply layer 12 by applying a voltage Vd between an ohmic electrode 11 and a metallic thin-film electrode 15, a diode current Id flows, and since an insulator layer 13 has high resistance, the major part of the applied voltage is applied to the insulator layer 13. Electrons migrate inside the insulating layer 13 toward the metallic thin-film electrode 15, and some of the electrons which reached near the metallic thin-film electrode 15 are made to tunnel through the metallic thin-film electrode 15 by a strong magnetic field there and released into an outside vacuum. The film thickness of the insulator layer 13 is set at 50 nm or more, and the voltage is applied between the electron supply layer 12 and the metallic thin-film electrode 15 to release electrons. The electron supply layer 12 has a film thickness of 2.5 μm or more.

摘要： PURPOSE:To obtain an optical recording medium, which has excellent light resistance, by which a fine bit having an arranged shape is formed on recording and which has sufficient reproducing characteristics, by containing a phthalocyanine dyestuff and a light absorber having absorption in the wave range of a laser recording wavelength, in a recording film. CONSTITUTION:In an optical recording medium having a recording film on a substrate, the recording film contains a phthalocyanine dyestuff and a light absorber having absorption in the wave range of a laser recording wavelength. The light absorber is contained in the phthalocyanine dyestuff at 5-20wt.%. Light reflection by absorption is lowered remarkably and the trouble of the lack of playability is generated when the value exceeds 20wt.%, and the trouble of the fluidization of the optical recording film of original phthalocyanine is generated when the value is less than 5wt.%. The recording film containing the phthalocyanine dyestuff and the light absorber is coated through a spin coating method, etc. The recording film coated is approximately 40-100nm thick. A semiconductor laser having a wavelength of 760-830nm is favorable as laser beams applied to the recording medium.
