Abstract
Carbon nanotubes, which were made by DC arc discharge of a graphite electrode, were heat-treated at about 250°C in intermediate vacuum of 10−4 Torr and 10−2 Torr. Considerable thickening of carbon nanotubes and periodic morphology like that of living organisms were observed by scanning electron microscopy.Keywords
