摘要： A carbon nanotube is contacted with a reactive substance which is a metal or a semiconductor. The reactive substance is heated to diffuse atoms of the reactive substance into the carbon nanotube so that the carbon nanotube is partially transformed or converted into carbide as a reaction product. Thus, a heterojunction of the reaction product and the carbon nanotube is formed. For example, the carbon nanotube (2) is contacted with a silicon substrate (1). The silicon substrate (1) is heated to cause solid-solid diffusion of Si. As a result, SiC (3) is formed as the heterojunction. At least a part of a filament material of a carbon nanotube is irradiated with electromagnetic wave to deform the filament material.

摘要： The invention provides a nanometer sized carbon tubule enclosing a foreign material except for carbon. The carbon tubule comprises a plurality of tubular graphite monoatomic sheets coaxially arranged. The foreign material is introduced through a top portion of the carbon tubule. The introduction of the foreign material is accomplished after forming an opening at the top portion of the carbon tubule either by contacting the foreign material with the top portion of the carbon tubule together with a heat treatment or by an evaporation of the foreign material on the top portion of the carbon tubule together with the heat treatment. The foreign material is introduced only in a center hollow space defined by an internal surface of the most inner tubular graphite monoatomic sheet.
