Can I ask you some … 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! … 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 … 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 … 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
wow. very impressive wow. very impressive
