    摘要: It is to provide a thermodynamically and chemically stable dopant material which can achieve controls of the pn conduction types, carrier density, and threshold value of gate voltage, and a manufacturing method thereof. Further, it is to provide an actually operable semiconductor device such as a transistor with an excellent high-speed operability and high-integration characteristic. Provided is a dopant material obtained by depositing, on a carbon nanotube, a donor with a smaller ionization potential than an intrinsic work function of the carbon nanotube or an acceptor with a larger electron affinity than the intrinsic work function of the carbon nanotube. The ionization potential of the donor in vacuum is desired to be 6.4 eV or less, and the electron affinity of the acceptor in vacuum to be 2.3 eV or more.

    摘要: A carborane supercluster consisting of carborane (C2B10H12) as its constituent unit expressed as a molecular formula C2mB10mH12m-x, where x is a positive integer (i.e., x=1, 2, 3, . . . ) and m is an integer greater than unity (i.e., m=2, 3, . . . ). The parameter x represents the count of removed or detached hydrogen atoms. The parameter a represents the count of the clusters linked together. To produce the supercluster, carborane (C2B10H12) is ionized in a reaction chamber to generate carborane ions and then, the carborane ions thus generated are successively reacted with the remaining neutral (i.e., non-ionized) carborane (C2B10H12), thereby generating the carborane supercluster. Preferably, the cluster of the carborane consists of at least two of o-carborane, m-carborane, and p-carborane.

    摘要: A mixture of carbon nanotubes and impurity carbon materials, which include carbon nanoparticles and may possibly include amorphous carbon, is purified into carbon nanotubes of high purity by utilizing a significant difference in oxidizability between the nanotubes and the nanoparticles. The mixture is pulverized and heated in the presence of an oxidizing agent at a temperature in the range from 600.degree. to 1000.degree. C. until the impurity carbon materials are oxidized and dissipated into gas phase. The nanotubes remain almost unoxidized except for loss of some lengths from the tube tips. It is suitable to perform the heating in air or oxygen.
