著者：J. Azuma, M. Itoh, M. Koike, M. Kamada and M. Endo題名：Infrared absorption change in single-walled carbon nanotubes observed by combination spectroscopy of synchrotron radiation and laser発表情報：Journal of Synchrotron Radiation 巻: 13キーワード：Laser SR Infrared Carbon nanotube概要：抄録：The Drude tail due to photo-excited carriers in single-walled carbon nanotubes (SWNTs) has been observed in the mid-infrared region by using combination spectroscopy of synchrotron radiation and Ti:sapphire laser. It is found that the density of photo-excited carrier increases as the sample temperature is raised from 12 to 300 K, and its lifetime is of order of minutes at 300 K. These facts suggest that the movement of photo-excited carriers is largely affected by some extrinsic defect, thus resulting in the long-lasting Drude reflection in SWNTs.英語フィールド
