Abstract

We prepared string like assemblies of aligned single-wall carbon nanotubes (SWCNTs) in a (6, 5) nearly single-chiral state. We observed that by simply adjusting the temperature and incubation time of SWCNT monodispersed solutions, string-like assemblies of aligned SWCNTs could be generated. Polarized Raman and scanning electron microscopy measurements clearly indicated that the SWCNTs were aligned parallel to the string axis. These assemblies exhibited good field-effect performances, exhibiting an on/off ratio of 6.8 × 10 3 and a maximum mobility of 106.5 cm2 V-1 s-1.
