Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study is simultaneous control of in-plane alignment and chirality of single-walled carbon nanotube (SWNT). SWNT was grown on ST-cut quartz substrate under the irradiation of 800 nm free electron laser (FEL). The surface image indicates the growth of in-plane aligned SWNT. The radial breathing mode (RBM) peaks were observed only with 785 nm excitation laser, indicating that the FEL irradiation enhances the growth of SWNTs having specific bandgap, which corresponds to the photon energy of the FEL. However, we got not only semiconductive SWNT with a diameter of 1.97 nm but also metallic one with a diameter of 1.59 nm. The diameter control is necessary for growth of only semiconductive SWNTs. In order to control the diameter of SWNT, we prepared catalyst with three different pull speed, expecting different catalyst diameter. The larger diameter and higher density were observed with higher pull speed, while the heat treatment made the difference much smaller. Then the SWNT showed almost the same morphology and diameter. Further investigation is required on the heat treatment for the catalyst.
