Abstract (in Japanese) (See Japanese page) 
(in English) Single wall carbon nanotubes (SWNTs) are characterized as metals or semiconductors depending on their diameter and chirality. For applying SWNTs to the nanoscale electronic devices, the chirality must be controlled. We propose a novel technique to control the chirality using free electron laser (FEL) irradiation. The irradiation of FEL with the wavelength of 800 nm can be effective to enhance the synthesis of semiconductive SWNTs selectively with the specific chirality to the SWNTs with the 1.1 nm in diameter. In the SWNTs grown under 800 nm FEL irradiated the peak of radial breathing mode (RBM) was observed only diode laser (@785 nm). Effect of 800 nm FEL irradiation during ACCVD was advanced semiconductive SWNT growth.
