ABSTRACT:
The present invention provides an apparatus for manufacturing a carbon nano-tube tip comprising an AC/DC voltage supply, a metallic or semiconductor tip, an amperemeter, and a metallic vessel connected to the tip and the amperemter, wherein the metallic vessel is used as the electrode and define a groove therein filled with a carbon nano-tube solution. The present invention also provides a method for manufacturing a carbon nano-tube tip wherein carbon nano-tubes dispersed in a solvent are attached by electrophoresis to the end of a metal tip or semiconductor tip by using as an electrode a metallic vessel having a groove therein.
