    摘要: A carbon film of the present invention has an elongated needle shape whose radius decreases toward a tip. The shape is, preferably, a shape in which a field concentration coefficient β in the Fowler-Nordheim equation is expressed by h/r where r denotes the radius in an arbitrary position and h denotes height from the arbitrary position to the tip.

    摘要: The present invention provides a carbon film that is remarkably excellent in current voltage (IV) characteristics. This is achieved by way of a carbon film structure, two or more carbon film assembly units 12 are formed on a substrate 10. The carbon film assembly units 12 comprise: a stem-like carbon film 14 which is made into a film in the shape of a long and thin needle; and a branch-like carbon film cluster 16 which is made into a film so as to surround the stem-like carbon film 14 from the halfway to the lower part of this stem-like carbon film 14. The stem-like carbon film 14 has the shape of a long and thin needle having a configuration which has a spiral streak-like step part 18 towards the distal end at the circumference face of a near tip and in which the radius becomes small as going to the distal end.

    摘要: Provided are an electron emitting body having a high electron beam density and an X-ray emitting device embedding the electron emitting body. The electron emitting body has a substrate, the surface of which forms a concave surface, and a carbon film comprising a large number of projections made of carbon and expanded two-dimensionally. The carbon crystal grows such that first a swell portion (22) gradually becomes larger and then a needle-like portion (23) grows from the head of the swell portion (22). The needle-like portion (23) has a graphene sheet obliquely wound therearound in a multi-layer fashion and has a hollow inside. The axis of a carbon projection (21) thus formed is substantially orthogonal to a line tangent to the concave surface (11), so that the axes of a plurality of the carbon projections (21) intersect with each other at the focal point (F) of the concave surface (11).
