Nanotube length control method

摘要

A nanotube length control method involving a nanotube and a discharge needle so that the nanotube with its base end portion fastened to a holder and its tip end portion caused to protrude is set so as for its tip end to face the tip end of the discharge needle. A voltage is applied across the nanotube and the discharge needle so that an electrical discharge is caused to occur between the tip end of the nanotube and the tip end of the discharge needle, thus cutting down the tip end of the nanotube by this discharge, and it is possible to control the length of the tip end portion of the nanotube.
