Multi-Walled Carbon Nanotube Oscillator Behavior Analysis Using Classical Molecular Dynamics Simulations

Abstract

Multi-Walled Carbon Nanotube Oscillator Behavior Analysis Using Classical Molecular Dynamics Simulations Jeong Won Kang Department of Computer Engineering, Chungju National University, Chungju 380-702 Jun Ha Lee Department of Computer System Engineering, Sangmyung University, Chonan 330-729 (Received 10 April 2008) The behaviors of multi-walled carbon nanotube (CNT) oscillators were investigated by means of classical molecular dynamics simulations. As the number of walls increases, the number of frequency peaks also increases because the walls are coupled with each other. The frequency corresponding to the maximum peak height of each frequency spectrum for the multi-walled CNT oscillators is less than the frequency for the double-walled CNT oscillators. The highest frequency of the multi-walled carbon nanotube oscillators is greater than the frequency of the double-walled carbon nanotube oscillators. The amplitudes for higher frequencies tend to decrease as the number of walls increases. PACS numbers: 61.46.+w, 66.30.Pa, 83.10.Rs
