    Can I ask you some questions?At what temperature is this happening? What is the scale and how did you mount it on the tip?Thanks!

    o matiak200,

    The nanotube is about 4 to 5 micron in length and 25 nanometer in diameter. The video was taken at room temperature. One can mount the tube by p ing a current from the wire across the nanotube to ground.

    Very impressive!Have you published that?I’m myself trying to grow CNTs in situ on the extremity of sharp Ni tips and it’s really complicated!

    No, there are a few labs published mounting single nanotube on tungsten or nickel tips already. See a recent paper in J. Vac. Sci. Technol. B 25(2) Mar/Apr 2007 (under EXPERIMENT on page 561).

    Did your nanotubes look like spaghetti when you grow them on Ni tip?

    In fact I only observe them by field emission microscopy so I cannot tell you if they look like spaguetti ;) But I will try soon to observe them by SEM/HRTEM
