초록

본 논문에서는 고전적인 분자 동역학 시뮬레이션을 통해서 다양한 길이를 가진 이중벽 탄소나노 튜브로 만들어진 초고주파 나노 기계 공진기의 주파수 변동 특성을 분석한다. 분석의 목적은 이중벽 탄소나노 튜브 벽의 길이에 따라 변동하는 공진기의 주파수 분석이다. 실험 결과, 주파수 변동이 여러 가지 외벽 길이 값 L10에 대해서는 내벽/외벽 길이 비율 L5/L10의 함수로 최대 주파수로 정규화된 공진 주파수가 Pearson VII 함수에 잘 맞고, 여러 가지 내벽 길이 값에 대해서는 외벽/내벽 길이 비율의 함수로 최대 주파수로 정규화된 공진 주파수가 Gauss 분산 함수에 잘 맞는 것을 보여준다.

In this paper, we have investigated ultrahigh frequency nano-mechanical resonators, made of DWCNTs with various wall lengths, via classical molecular dynamics simulations. We have aimed our analysis on the frequency variations of these resonators with the DWCNT wall lengths. The results show that the variations can be well fitted by either the Pearson VII function when the resonant frequency of normalized by its maximum frequency is plotted as a function of the inner/outer wall length ratio L5/L10 for different values of the outer wall length L10, and the Gauss distribution function when the resonant frequency of normalized by its maximum frequency is plotted as a function of the outer/inner wall length ratio for different values of the inner wall length.
