PROBLEM TO BE SOLVED: To realize formation of a carbon nanotube in a high yield with an excellent mass productivity, by enabling selective formation of a carbon nanotube with a semiconductive nature. SOLUTION: After a carbon nanotube 21 is grown between electrodes 14a and 14b through crosslinking, a voltage V<SB>2</SB>is applied between the electrodes 14a and 14b by a voltage-applying mechanism 3. Here, the value of the voltage V<SB>2</SB>is one that cuts and breaks a carbon nanotube with a metallic nature (in this case, corresponds to a current density of≥1,000,000 A per unit cm<SP>2</SP>applied through the carbon nanotube) and leaves the carbon nanotube with the semiconductive nature intact. This enables selective formation of the carbon nanotube 23 with the semiconductive nature. COPYRIGHT: (C)2005,JPO&NCIPI |
