Nanogripper using Carbon Nanotube

摘要

Nanogripper was made from two nanotips and the nanotip is composed of tungsten tip and carbon nanotube. The tungsten tip was made by the electrochemical etching with KOH solution. The initial and final diameter of tungsten tip were 500 micrometer and several micrometer respectively. The carbon nanotube is multi-wall carbon nanotube grown on the Al_2O_3 by chemical vapor deposition. The average diameter of carbon nanotube is 130 nanometer. The procedure to make nano-tip is monitored by optical microscope of two thousand magnifications. The length of carbon nanotube in nanotip was controlled by the electrochemical etching to satisfy in special application. The nanogripper was made by the fixing stage that has three degree of freedom.
