摘要： According to the present invention, there are provided a novel graphite-like three-dimensional structure which has a partial structure bent-up with such a steeper curvature than that observed for a carbonaceous material having a conventional nanosize three-dimensional structure such as fullerene and nanotube, has such a feature as light weight and high mechanical strength, as well as a process for manufacturing the same. In the present invention, under a high temperature and a low pressure, a plurality of nanosize graphite layer fragments are forced to coming into collision at a high speed in a relative orientation where the layer planes are not set in parallel to form a carbonaceous three-dimensional structure where at least a plurality of graphite-layer-like layer planes having a hexagonal network structure made up of carbon are arranged such that they mutually cross or are in contact with each other and at the sites for the contact between the plurality of layer planes, connections via carbon-carbon covalent bonds are aligned in the shape of a cross-line.

摘要： The present invention provides a method of selectively extracting metallic armchair carbon nanotubes alone from the mixture of carbon nanotubes of mixed chiralities, wherein vacant lattice defects are removed from armchair carbon nanotubes alone using the fact that the vacant lattice defects of zigzag carbon nanotubes are hard to diffuse in the axial direction of nanotubes compared with those of armchair carbon nanotubes. Since vacant lattice defects remaining on zigzag carbon nanotubes are active, the tube structures are easily destroyed and decomposed by oxidation etc. Thus it is possible to extract armchair carbon nanotubes alone from the mixture of carbon nanotubes of mixed chiralities.

摘要： To realize a transistor with a channel and a gate, both being formed with nanotubes, by joining the nanotubes in the form of SP3 bonding, a substrate, on which a pair of source and drain electrodes 27, and a gate terminal 28 are formed, is prepared (Fig. (a)), and then a catalytic layer 20 is formed at the one of the source and drain electrodes 27 (Fig. (b)). A first CNT 23 is formed (Fig. (d)) between the pair of source and drain electrodes 27 by growing the CNT (Fig. (c)) in which the catalytic layer 20 is a core. A second CNT 24 is picked by a holding means 25, and after a cap is eliminated and an opening portion is cleaned using the electron beam as needed, the opening portion is contacted to the side of the first CNT 23, thereby joining the two CNT (fig. (e)). The other end portion of the second CNT 24 is positioned at the gate terminal 28 (Fig. (f)). End portions of the CNT are fixed on the electrodes and the terminal by selectively irradiating metallic ion.
