초록

짧은 바깥쪽 탄소 나노튜브를 가진 이중벽 탄소 나노튜브 공진기의 경우, 자유로운 끝은 긴 안쪽 벽의 진동에 중요한 역할을 한다. 짧은 안쪽 탄소 나노튜브를 가진 이중벽 카본 나노튜브 공진기의 경우, 안쪽은 부드러운 코어로 작동하여 기본 주파수가 이들의 길이에 의해 영향을 받는다. 본 논문에서는 서로 다른 길이를 가지고 나노튜브로 구성된 이중벽 탄소 나노튜브 공진기의 주파수 변화를 분석한다. 분석 결과, 안쪽 혹은 바깥쪽 탄소 나노튜브 길이를 제어하는 다양한 주파수 소자를 구현하는데 널리 응용될 수 있을 것으로 판단된다.

For a double-walled carbon nanotube resonator with a short outer nanotube, the free edge of the short outer wall plays an important role in the vibration of the long inner nanotube. For a double-walled carbon nanotube resonator with a short inner nanotube, the short inner nanotube can be considered as a flexible core, thus, the fundamental frequency is influenced by its length. In this paper, we analysis frequency variation in ultrahigh frequency nanomechanical resonators based on double-walled carbon nanotubes with different wall length. This results will widely apply to the realization of frequency devices controlling the length of the inner or outer nanotube.
