Molecular dynamics study on resonance frequency shifts due to linear density of nanoclusters encapsulated in carbon nanotubes

► Fundamental resonance frequency shifts of the cantilevered carbon-nanotube-resonators encapsulating finite nanoclusters. ► As the linear mass density of the encapsulated finite nanocluster increased, the frequency-shift-range also increased. ► Linear density of the encapsulated nanocluster as an important parameter to analyze the vibration features of carbon-nanotube-resonators.
