The carbon nanotube field-effect transistors show the hysteresis characteristic in their electrical characteristics owing to the amorphous carbon around the carbon nanotube. It is shown here the reduction of the hysteresis characteristic by the refining process applied repeatedly to the carbon nanotube. Moreover, after the refining processes, the transconductance of carbon nanotube field-effect transistor becomes 2.0μS the ten times larger than before the refining process. Almost all carbon nanotubes without the refining processes, grown by thermal chemical vapor deposition, show the p type semiconductor characteristics. After the refining processes on the other hand, almost all carbon nanotube show the ambipolar type semiconductor characteristics.
