Abstract:

The perfunctory and geometrical properties of carbon nanotubes (CNT), nanocantilevers beam from Multi-walled carbon nanotubes (MWCNT) substance were investigated in this lesson. Multi-walled nanotubes (MWCNT) consist of multiple rolled layers of graphene. There are two models that can be used to explain the structures of multi-walled nanotubes. In the Russian Doll model, sheets of graphite are agreed in concentric cylinders, e.g., a (0, 8) single-walled nanotubes (SWNT) within a larger (0, 17) single-walled nanotubes. The interlayer expanse in multi-walled nanotubes is close to the expanse between graphene layers in graphite, approximately 3.4 Å. In this case, the results showed that the first resonance frequency ω0 of the nanocantilever beam from the measured MWCNTs' dimension and spring constant is about 100 MHz. Due to the exceptional mechanical and geometrical characteristic of MWCNT, the first resonance frequency found is high compared to that one made from mica (ω0 = 20 Hz) or silicon (ω0 = 14 KHz). The result obtained is expected to have potential applications in nanoelectromechanical system (NEMS) working with high resonance frequencies.
