摘要：
An understanding of thermal vibrations of carbon nanotubes is key to their application as high-frequency mechanical resonators. To this end, we calculate the free thermal vibrations of cantilevered carbon nanotubes using molecular dynamics and explain the resulting power spectral density of the tip displacement with equilibrium statistical mechanics and continuum beam theory.
