Abstract
Single-walled carbon nanotubes (SWCNT) prepared by a DC-Arc-Discharge and p urified by a hydrothermal treatment followed by several steps of procedures including heating, burning, extracting and acid-washing are investigated b y a conventional STM technique morphologically and spectroscopically. The e lectical resistivities of compacted pellets (mats) of SWCNT are measured as a function of temperature in the range from the room-temperature to 1.5K. The behaviors seems to be essentially originated in the metallic nature of individual SWCNT.
