摘要:
A carbon film having a large electrical conductivity is produced at a comparatively low substrate temperature by a method comprising forming the carbon film from a hydrocarbon by an ion beam method and heating the substrate at a temperature of 400.degree. C. to 1,200.degree. C.
摘要:
A method for forming a conductive graphite film comprises the steps of forming a carbon film on substrate material heated to 700.degree. C. or higher through a plasma discharge using hydrocarbon gas as raw material and subjecting the film to heat treatment at temperatures exceeding 1,500.degree. C.
摘要:
A carbon film having a larger electrical conductivity is produced on a substrate by an ion beam method comprising steps of ionizing an organic compound having at least one substituent selected from the group consisting of a carbonyl group, an aldehyde group, an acyl group, an acid anhydride group, an amino group, a nitro group, a hydroxyl group, an alkoxyl group, a thiol group and a halogen or a cluster of said organic compound with an ion beam which accelerates ionized species towards a substrate by an electric field and forming a carbon film on the substrate.
摘要:
A stabilized carbon cluster conducting material comprising (i) a core comprising a conducting or superconducting carbon cluster and (ii) a sheath covering the core; a device comprising a substrate having thereon a film of a conducting or superconducting carbon cluster covered with a protective film capable of substantially preventing permeation of oxygen and water in the atmosphere; and processes for producing the stabilized carbon cluster conducting material and the device.
摘要:
An organic charge transfer complex comprising an electron donor and an electron acceptor, the electron donor is at least one of bis(oxapropylenedithio)tetrathiafulvalene represented by formula (1): ##STR1## and bis(thiapropylenedithio)tetrathiafulvalene represented by formula (2): ##STR2##
摘要:
A carbon cluster film has a precisely controlled stable electrical conductivity which does not deteriorate in a short period of time in air. Such a carbon cluster film having a stable electrical conductivity is formed by introducing an impurity into a thin film of fullerenes by ion implantation. The fullerenes include C.sub.60, C.sub.70 or the like.
摘要:
A process for producing a plastic optical fiber which consists of a core made of a homo- or co-polymer of alkyl methacrylate and a cladding made of a fluorine-containing polymer, which process comprising forming the cladding around the core and irradiating the optical fiber with an electron beam, the optical fiber produced by the process being used at a temperature higher than 80.degree. C. without significant loss of light transmission.

摘要:
An organic superconductor comprising an electron donor and an electron acceptor and a process for producing the same, the organic superconductor being produced by performing an ultrasonic wave-assisted reaction between the electron donor and the electron acceptor as they are dissolved or dispersed in a solvent in a substantially oxygen-free reaction vessel.
