Abstract

Official abstract text for this publication.

A carbon nanotube (CNT) resonator includes: a first CNT having a first end and a second end both fixed to a substrate; and a second CNT having a first end fixed to the substrate. The second CNT creates a Van der Waals (VdW) bond with the first CNT where the second CNT overlaps the first CNT. A length of the VdW bond along a distance between the first and the second CNTs oscillates based on a DC voltage applied between the first end of the first CNT and the first end of the second CNT. An electrical current passing through the first and the second CNTs using the VdW bond oscillates based on the oscillation of the length of the VdW bond.

First claim

Opening claim text (preview).

What is claimed is: 1. A carbon nanotube (CNT) resonator comprising: a first CNT having a first end and a second end both fixed to a substrate; a second CNT having a first end fixed to the substrate, wherein the second CNT creates a Van der Waals (VdW) bond with the first CNT where the second CNT overlaps the first CNT, a length of the VdW bond along a distance between the first and the second CNTs oscillates based on a DC voltage applied between the first end of the first CNT and the first end of the second CNT, and an electrical current passing through the first and the second CNTs using the VdW bond oscillates based on the oscillation of the length of the VdW bond. 2. The CNT resonator according to claim 1 , wherein the second CNT functions as a cantilever. 3. The CNT resonator according to claim 1 , wherein a frequency of the electrical current oscillation negatively depends on an angle formed between the first and the second CNTs, and the angle is in a range of 0°, in which the first and the second CNTs are parallel, to 90°, in which the first and the second CNTs are perpendicular with respect to each other. 4. The CNT resonator according to claim 1 , wherein the first and the second CNTs are metallic. 5. The CNT resonator according to claim 1 , wherein the first and the second CNTs are semiconducting. 6. The CNT resonator according to claim 1 , wherein the first and the second CNTs are straight. 7. The CNT resonator according to claim 1 , wherein the substrate is an insulator. 8. The CNT resonator according to claim 1 , wherein the first and the second CNTs are single-wall CNTs.
