| Research Abstract |
We planed to fabricate a linear oscillator consisting of an outer layer of a dumbbell-shaped CNT (two thick parts at both ends and one thin part in the middle) and an inner capsule of a short CNT with electric charges, which can operate at a frequency as high as a GHz order by an external electric field. Then, using the oscillator we planned to investigate the mechanism of energy dissipation in sliding between two carbon nanotube (CNT) layers and establish a designing principle of the oscillator.
We started to develop component technologies and a required facility to fabricate the oscillator, and realized an electrically charged CNT capsule and a dumbbell-shaped CNT. However, we did not reach the final structure of the oscillator and thus could not investigate the mechanism of energy dissipation in the electric drive oscillator.
